Thank you! I spent some time before the jam fighting with collision resolution code in a game for TIC-80, and I used the algorithm from there with a couple of tweaks. Here’s the repo for that game (the README list some of the resources I went through): https://github.com/desttinghim/tic80platformer
The most useful resource for me in the end was https://jonathanwhiting.com/tutorial/collision/
