Hi everyone I'm just posting our game jam here for others to check out. We used Godot and a great pixel art AI plugin for Aseprite that I found called PixelLab. I found old Russian folk midis and used an app called GXSCC to convert them to chiptune sounding songs. As a bit of an easter egg you can also select the USSR anthem in options.
We're looking to expand the game so any suggestions are welcome. Godot 4 was a bit of a pain to work with but hopefully will be more developed going forward.
I can recommend the Seattle Indies Slow game jam next year, you don't have to be in Seattle to join.
Edit: Someone has been impersonating us in the comments on itch, I am one developer here and the other dev AndroidOverlord is the other on itch.io - anyone else responding is not associated with Rabbitariat.
I'm not thrilled Aseprite isn't FOSS but if anyone still wants to use it, I was able to compile it myself using this docker container for Linux: https://github.com/nilsve/docker-aseprite-linux . There are similar tools for other OSes.
I wasn't aware of Libresprite so thanks for that, but I don't think it works with the PixelLab plugin I use.
I used this website, JSFXR, to make 8 bit sound effects: https://sfxr.me/ And GXSCC to convert MIDIs to chiptunes: https://meme.institute/gxscc/ not fully free/FOSS but OK for my purposes. GXSCC works well under WINE on Linux.
