I know you stated you didn't have time to finish the game, but I honestly really like what you have! Despite the simple look I think the game manages to have a cool looking style with the limited palette and pixelated filter as well as interesting gameplay. There were a few occasions where I struggled with the perspective, where the wall and the floor looked like the same colour and I couldn't tell where I was supposed to stand, and signposting that you're supposed to fall in the hole would help too (it looked to me like a pit that would kill me) but given you didn't finish in time I think you did really well!
