I think I hit a bug the first time I played, I only had 1 generator and ran out of doors to go through, not sure if it stopped generating or an enemy was outside the map or something, but I enjoyed the gameplay enough to try it again and it worked properly then.
Fun aesthetic, and the art worked well. The guns/shooting felt good but maybe a little too easy to scale up - I'm not sure what I was spending in the shop but apparently I had a lot of it. Music and sfx were decent with the exception of some crackling/peaking at times. I wish the big spinny things did damage or knocked enemies around, I think that would've helped with fitting the theme better.
Enjoyed the game overall and would like to see it developed further, however there is one major major issue in that you can't pet the shop cat, would pay for cat petting DLC.
