Awesome entry, i enjoyed it! Movement mechanic is fun, music is great and shot sfx is very satisfying. I missed the ability to switch turret position from one side to another, to move back, or to deal with cases like when you stuck into the wall. Restarting the chapter after you lost all buttery charges feels like too much for me. It's hard enough, why punish your player so badly? :)) I guess, I just not hardcore enough for such things :)
