Dutch roboticist by day | indie game dev by night

I post updates of my video game development and other nerdy obsessions

Please check out and wishlist
Broom and Boom : s.team/a/3673790
It Digs Up : s.team/a/3554000

Been working on the visuals for the giant goblin mech. Next steps are the goblin king pilot in its chest and for each limb to move and attack independently

Consider a wishlist : s.team/a/3673790

I want the final boss of Broom and Boom to be this shoddily constructed goblin mech made of random pieces of wood and bolts

Currently working on the head. Still needs and attack. Bullets from the eye sockets perhaps?

Been working on Broommancy ,the magic spell that turns your broom-like (in this case, a giant sponge) into a bullet and increases your collision damage

I like the colorful trail it leaves behind

There are 10 000 combos (10 of spells, spirit animals, weapons and brooms each) in my game, meaning some edge cases that need a little extra code

One of them is the throwable shield combined with the spell that turns all bullets into fireballs

Hence, the exploding fire shield

Making a first pass at the final enemy

It's a giant mechanical goblin, with the goblin king in its torso, its center protected by destructible limbs

Never made a boss enemy before. Complexity goes up, which seems fair for the culmination of the game

For #screenshotsaturday, let me show an unlockable customization combo for the Witch

The minigun, with Bulletmancy (turns bullets to fireballs), spirit animal Clippy (increase fire rate) and the mop and bucket (absorb enemy health on kill)

Game balance at its finest

Making the 8th spell in my game, Chromamancy. Basically a zappy, multicolored mine

Consider wishlisting if you think zapping goblins on brooms sounds like a good time : s.team/a/3673790

Working on the final weapon unlock for the witch, the AC130. Use a laser to lock onto goblins and call down a strike

I love doing #indiedev

Thank you for 800 followers!

To celebrate, here is the witch having 800 cackles!

I got a demo out for #steamnextfest, consider checking it out and giving it a wishlist if cackling on broom-likes appeals to you s.team/a/4051030

Made a first pass at the 7th spell you can unlock, summoning a circle of goblin seeking knifes

It needs some more work. Perhaps fly with the player for a bit, some streaks in the sky as they home in, definitely more visible impact

After finishing the demo for 'Broom and Boom', I can now continue with the development of the game itself.

The joy of #indiedev is that ideas like 'a witch in a bucket and mop, with a minigun' can be implemented just because you want it to exist

This is a special #wishlistwednesday for me, because it is the first time I got a demo out for people to try!

Please consider checking it out and let me know what you think : s.team/a/4051030

Often, bugfixing is making improvements to mechanics, preventing crashes, observing AI behaviours, etc.

And sometimes it is checking that the game still functions if the player doesn't press any buttons for a good while

I made a new trailer with updated visuals for Broom and Boom, to coincide with the demo release next week. I look forward to people being able to play it

Had issues with goblins flying into you from off screen. So now I made some arrows that point where non-visible enemies are

It removes some uncertainty, but helps with planning aerial maneuvers, which ultimately serves the game experience I think

Just played a feature complete version of my demo for the first time. Milestone feels good

It is about half an hour long if you want to unlock everything, like the robot vacuum, chainshield and chronomancy

The witch heals by cackling (obviously). Cackling prevents you from accelerating with your broom, so you start dropping down

Doesn't prevent you from firing your gun in freefall though
