Happy 10th Anniversary, UNDERTALE! To celebrate the occasion, here's a preview showcasing one of Demo v3.0's random encounters: Moulder!
We originally planned to have a longer Crystal Mines teaser video for today, but need more time before it's done -- once it's ready, we'll post it!

WE'RE never GETTING OUT OF RUINED HOME WITH THIS ONE 🔥🔥🔥
As we continue working on low-priority sprite revamps alongside more important v3.0+ tasks, we've been finalizing our Aaxel resprite! Still subject to change.
Work-in-progress new sprites of TS!UNDERSWAP's Aaxel (left), compared with his current sprites (right.) They now utilize more dynamic poses, rather than static directional ones. These have been done by Depresso, Beethovenus, Chip Potato, and others.

Here's a sneak peak of a future update!
All of the Boogiemen's new battle sprites are finished and implemented in-game -- all we have to do is polish things up, fix some issues, and manually backport everything from the Demo v3.0+ branch to Demo v2.0's.
Then, the new music... and it's good to go!

All new sprites for the Boogiemen (excluding a new fight cloud animation at the end) are finished and being implemented in-game!
We're currently nearing completion with this on the Demo v3.0+ branch, and will need to backport everything to the 2.0 branch afterwards.

Reminder that we have a website! We just made some small improvements to the FAQ page -- to better describe what's listed on our Support page (i.e. info on Mac support ending, etc.), and current information on language support.
We get a ton of questions about these, hope it helps! teamswitched.dev

Okay, so the GIFs didn't work for some reason. Let's try that again! First, Papyrus.

Here's a quick bulletpoint list going over the rest of what we covered, but didn't want to show anything off for:
That was a lot! To finish off this section, here's a few more things we've been working on -- we either don't want to show these off currently, or feel there isn't much point to showcasing them: - Reworks to Bugerpant's overworld sprites for consistency with his look from Deltarune (still in early stages, low priority given how many sprites we'd need to change.) - Reworks to Mad Dummy's battle sprites for consistency with our current art style (still in early stages, higher priority given Dummy-related content in Crystal Springs.) - Reworks to Flowey's facial expressions (incl. number thereof) to better differentiate it from Undertale's Flowey (not implemented in-game yet; condensed many of its facial expressions, need to refine and figure out some other ones.) - Slight polish to the Crossbones "pretend" post-fight scene for better consistency with overall plans and design intentions (implemented in-game.) - Chara now has armor sprites when grabbed by Koffin-K following the Mad House chase (these have not been implemented in-game just yet.)

And finally, we decided to give Muffet a dialogue SFX! Since she has a good deal of in-game content featuring her (i.e. battle, shop, hangout), we felt it made sense to add this detail which set her aside from other minor characters.

New battle buttons! These were made by LuneyToons, with the exception of a brand new button variant made by Chip Potato -- when the player has run out of ITEMs, this will be reflected in-battle with an empty bag icon. Nothing major here, just little added details!

Harry and Larry's re-styled battle sprites are almost finished! There's just a few more we need to do -- to learn more, read the full section from this devlog (pictured below.)
This has been a massive collaborative effort, and we're looking forward to getting this into players' hands!
An animated GIF of Larry from TS!UNDERSWAP, laughing. These new sprites were made by LuneyToons. As we've mentioned before, the new battle sprites for Harry and Larry are almost fully finished! To put this in perspective: we've made 23 dialogue portraits (with 7 new ones), 26 battle heads (with 3 new unused ones), and 56 battle sprites (including new variants depending on the route.) Most of the work is due to how many sprites were reliant on the ones which needed the most changes -- and so when the "base sprites" were redone, we needed to redo or heavily modify all sprites which relied on the look and posing of them. All that's left now are: - Harry's swipe attack (3 sprites) - Harry laughing (2 sprites) - Harry and Larry reacting to hitting each other (1 for Harry, 2 for Larry) - Harry reacting to a shove forward (2 sprites) - Harry and Larry's "fight cloud" animation (unsure right now, we plan to make an entirely new animation for this one instead of making it code-based.) This has probably been one of the biggest collaborative efforts for a specific task with this project thus far, combining the efforts of Devilredd, LuneyToons (who made Larry's laughing animation above), Chip Potato, DepressoKnows, Beethovenus, SuperKirbylover, and EllisBros to get these done. We're not even finished implementing all of them in-game yet, either! We previously mentioned how these changes were being targeted for the eventual Demo v3.0 release, given the following: The amount of changes and fixes to existing content in-game (i.e. positioning, animations) will need testing to make sure there are no bugs created as a result, especially those which may impact other aspects of the game in unexpected ways. The development branches for v2.0 and v3.0 are separate, as they use different versions of GameMaker, and so the changes would need to be applied across both branches and tested accordingly. However, because we want to get these into the hands of our players sooner than later -- since Demo v3.0 is nowhere near complete, and will take a good while to get done -- we're hoping to re-target these changes for a Demo v2.0 update, but we cannot promise this nor give an estimation on when this will occur. Thank you again for your patience with this, and we'll make sure to keep you all updated!

As part of the last changes, we've also made a new sprite for the Temmie plush in Asgore's house -- this one was made by DepressoKnows.

Next, Temmie! They received a complete overhaul to their battle and overworld sprites -- maintaining stylistic consistency with the other Temmies' sprites, and the way our visual style has progressed as a whole.
These were made by Beethovenus, DepressoKnows, and LuneyToons!

Want a quicker look at everything? No problem! 🧵⏬
First up were Papyrus's dialogue portraits and battle heads, which were modified to retain his angular look from Undertale. We showed these off here before, but here's a new GIF version! These edits were done by DepressoKnows.

Here comes another! Every now and then we like to make some touchups to earlier material -- primarily to maintain stylistic consistency throughout the game as it develops further, and sometimes for some extra flair.
It's Temmie! (may bite)

Papyrus fans, rejoice! We fixed him.

Thank you so much to everyone who's enjoyed this project, and stuck around for so long! We hope you all have Happy Holidays, and a very Happy New Year!
Our official translations for Spanish (Español), Brazilian Portuguese (Português Brasileiro), and Dutch (Nederlands) are still in-progress, and will ideally be released whenever they're ready. (These are done by hobbyist translators, so please be patient!) We're also in the process of discussing avenues for which community-created localization patches could be officially added to the game, including a list of guidelines (i.e. submission requirements, quality standards, etc.) It'll take us a bit to iron this out, so please give us time! In case you haven't seen, we're now using Bluesky! This will be one of our primary avenues of communication going forward (rather than Twitter.) We've also been a bit more communicative in our Discord server this year -- including a new Community Spotlight channel we've made for easily shouting out fanworks! Feel free to join if you want! Thanks for tuning in, and we'll see you guys next year! - Beethovenus and Team Switched An image depicts Spep wearing a Santa hat, and the Annoying Dog wearing reindeer antlers and a red Rudolph nose.
