This is one of the best of the jam! There's some really great polish to the game, I really liked the different skins, they added more incentive to play longer. One stat inversely effecting another is a great concept, and I'm glad you applied that to multiple stats. There is a great number of enemy varieties which spice up the gameplay, and the item drops were also interesting and added a lot of depth - I especially liked the time slow drop and the infinite bullet drop. The post processing effects added a lot of style to the game, and the sound effects were really chunky and satisfying. With what you set out to do, I can't find any noticable flaws!
