Welp the game is done (well it's an alpha demo) but after 38 days of serious coding sessions (~150k lines of code), it's in a good spot! If anyone wants to try it out let me know, I can share the access code (it's in closed testing for the moment while I get some feedback from friends). I'll publish it live sometime next week.
To recap, the game is using human made sound effects and music - the art is vector graphic shapes that are monochrome for now and the UI is simplistic. If theres enough hype, I'll invest in hiring artists and the like to make it a full game with all human made assets (the code is AI-assisted and it was quite clean after I touched it up with optimizations and conventions).
