While there's been a few shoot to move games in these jams before, I'm blown away that the game is procedurally generated and that you made such an immersive game in just 48 hours! I really liked the control scheme, it felt nice to control and it really streamlined the game. Mouse only is really comfortable to play!
I also like how the different enemies are so unique, and you have to employ different strategies for each. I had a blast (ba dum tsss) shooting away and dodging bullets, felt like a pro gamer everytime I shot someone and moved away just in time.
My only thing is that the items were a little confusing, I know you ran out of time to make a tutorial but that's my only critique. Other than that, I loved the use of just 3 colors and the MUSIC! I'm a music guy and I absolutely loved your soundtrack, so cool :)
