Hat mechanic was interesting, but felt inconsistent/difficult to control. I think mouse aiming gave too much variation in aiming, I never felt like I was able to consistently chain wall jumps. maybe just 8-way directional would be better? I never felt like I needed a full 360°s to aim, and it would still be a timing challenge. or maybe I need to get good...
The simple characters reminded me of old flash games and the end felt rather sudden, but I see in another comment that the game is unfinished. A shame, but I understand accidentally over-scoping.
