I loved all the art, music, sounds, and character designs! The dialogue snippets were fun too!
The way the mouse interacts with the player is a little odd... Like, when you're in scythe mode, the player always faces in the direction they walk, but faces in the direction of the mouse when standing still. But with the gun, you always face in the direction of the mouse no matter what iirc?
The scythe also needed WAY bigger hit detection, I'm not sure level 1 is possible at all.
The controls in general could have been improved... click is fire gun, R is reload gun, WASD to move, space to use scythe, tab and then click weapon to switch weapons... I think it would have been more smooth if those controls were condensed, like click to use scythe, and tab just cycles through your weapons without needing to click them, and reloading can honestly just be cut (it's not like it takes any time for the character to do, it's just a distraction for the player).
I really like the ideas in this game, I think it has a lot of potential!
