That was quite fun, even if initially the navigation was a bit tedious. I love the ending though, the text part exactly, feels very slapsticky to me.
I found a bug where if you try to shoot the revolver with both mouse and CTRL at the same time, your character can shoot multiple times on the same frame - this made it really easy to kill everyone at the ending.
I do wish the revolver packed a bit more punch visually, recoil, particles (on the enemies as well) maybe some better indicators of if an enemy was hit. I also found the saw blade guys' attack a bit unpredictabl - it sometimes seems to register as they are initiaing an animation and sometimes almost at its end
