The start was a bit weird, I wasn't sure if my game crashed, or it was the end or I just did something wrong. I'd remove that part. The rest of the game was actually pretty neat, especially for the first jam game. There was some depth and complexity and multiple mechanics, not bad at all. Controls were pretty clunky in a sense that it isn't easy to aim, but that's often the case in jam games and it wasn't too big of an issue in your game. Difficulty curve was good with just few sins here and there. Overall I liked this one, ended up playing for a while.
