Interesting and neat-looking game. I particularly like the shaders and changes to the music that get applied when you switch modes; I think they really sell the effect. It feels quite good to use the overdrive and I like how the second dungeon has mechanics that interact with it. However, the lack of any feedback (audio or visual) for reloading the gun doesn't feel very good and I think having some sort of cue for when you can or can't fire your gun is necessary for a game like this to feel good to play.
