The game page is pretty blatant that this is didn’t get finished, but for a game jam product it’s a nice tech demo. And really good for a first jam game! For the mechanics that are there (moving, shooting, random level generation), it all works really well. The enemy spawns might need a little bit of work (it was inefficient to shoot them all, so I ended up just avoiding them and having a horde flocked after me!) but otherwise I don’t think it needs too much more on the gameplay side. You could even keep the minimalist art style, just add some plot/story or objectives 😊
