Dang, for a first jam game this is oustanding! The audio, the visuals, the smoothness, the gameplay, the flow... all are great!
Unfortunately even after several attempts I wasn't able to win the game or even get close to winning due to not knowing what's happening. This game seriously needs a tutorial mode or a manual, or at least an easy mode, but I understand that it's a bit hard to implement all this in a short time span, especially considering you made all of this on your own. I'm still amazed by that fact, there's a lot of content in the game, including the AI! :D
P.S. "afterwords.md" was a fun and honest read. :)
