Thanks! I can't take full credit though, a lot of the initial UI design was done by Watabou on the original Pixel Dungeon about 12 years ago!

There aren't any direct links in game. While I did start it I'm not super active in moderating the discord anymore and so I don't want to link to communities and be responsible for them.

Thanks for the kind words! There are a few Pixel Dungeon communities, probably the most active on is the Discord: discord.gg/KBfMN8X

The exp bar was moved from the top of the screen to the left side just under the hero's portrait.

I don't intend to put in a toggle to revert this change, but obviously I won't do nothing if it's also making a significant users motion sick. Can you provide me any addition info about this for you, such as what device your using, how quickly it affects you, etc?

You could DM me there or on here, or send me an email: Evan@Shatteredpixel.com

The only official discord server is connected to my Patreon, but there is a public server for all Pixel DUngeon verisons, which includes a lot of discussion about Shattered: discord.gg/KBfMN8X

Honestly it's a difficult thing to give specific advice for. My best suggestions are to be careful of committing to a big project (start VERY small) and... just.. do it! It's better to get started mucking around than worrying about picking the best tools. Modding is a great place to start too.
