The art style did remind me of Downwell. Like Downwell, I thought this game really nailed using negative space to add texture to the world while using a limited color palette. I also thought the animations were super fluid. I did notice some odd visual artifacts: like sort of flickering white edges -- maybe around the edges of objects?
The gameplay sort of reminded me a bit of the action stages from the GameBoy version of Gargoyle's Quest. And I am always down for that.
Congrats on the good work.
Note: the best I did was 185, so I'm not sure if I missed out on some things farther along.
