Fun game, very satisfying when you manage to chain a big attack, and the choice between upgrading the gun or the saw adds a nice strategy element. Only problem I found was that the sfx were a little harsh, and when I tried to lower the volume the bgm started layering over itself. Also, when on fullscreen it can be a little difficult to notice when you have enough points for a level up, it would be nice if this was clearer. Definitely died a few times while scrambling to upgrade.
