Great prototype, you are really on to something here. I love the weapon copying mechanic, the unusual but intuitive control scheme, fast paced gameplay, minimal but juicy graphics and the funky soundtrack. This is quite an achievement in 3 hours!
I originally wanted 3-4 weapon/enemy types for the jam but stuck with making sure everything worked and added sounds/music instead. Thanks for playing and the kind words! I am actually looking forward to tweaking and updating everything after the jam.
