Isolation Game Jam

I made a game for the Isolation Jam game jam this weekend and you can try it out above! It’s a little shooter where you play as soap firing bubbles at nasty viruses!

Pick up the pink soap bubbles and don’t touch the viruses or you’ll get sick!

Source Code

I made the source code for my jam public on my own Gitlab repository!

Gamedev: Keeping Characters Upright

You gotta walk the walk and since we’re not trying to simulate a drunk walk here, I’ve been putting some work into making a character controller with walk/strafe on the left stick and look on the right stick, as is custom in these here gamin’ parts.

Success! We’re upright and working!

It wasn’t a quick and easy thing. I did a lot of searching and nobody else seems to have had the answer to what I wanted. This is what it looked like before.

Well, the first reply (2nd tweet here) is what it looks like.

I’m not sure why WordPress wants to embed both of them but only for the second tweet. Thanks for breaking my embed, WP!

Anyhoo, I hope this helps someone as I didn’t easily find the answer when I looked.
