FISHGUN

This is very well done for a free game. I assumed I paid money for it because it has full game mechanics, parkour-type movement with wall running and sprinting, and various weapons that get modifiers to create a bunch of fun alternative outcomes. The enemies are also highly varied in terms of movement patterns (Kinda like Doom) and the music is fantastic. It also isn't very balanced and doesn't have much replayability because the mechanics sort of break apart when the game gets super hard. The frenetic action of running and gunning is great, but when you are going at full seizure-inducing speed your success will be based on what weapons you've picked up more than any skill you've applied. Still, the final boss is good, there are a few challenging parts and for what it is it's very well done and creative.
