I think the team developed a nice scheme for a platformer; my favorite level was the first one. I believe that the current movement system favors more vertical levels, which is why I think the first one is the best. It was a good design choice for the enemies to not kill you directly but push you instead, this enabled me to sometimes use them as bouncing platforms. If the game ever gets expanded, this is a possible mechanic to explore further!
Congratulations on finishing the game!
