Really nice style and solid gameplay. Sadly this is hampered immensely by how punishing it is to learn the new abilities you unlock. I got to the second poison, after which I had to figure out how to walljump using it and the first one together. I managed to get over by spamming the two abilities but filling up your meter sends you back to the last checkpoint, so I was stuck.
I think the game would benefit from slowly introducing challenges after each unlocked ability and then combining them at the end, rather than making it near impossible to get past the first obstacle without fully understanding how to use your skills.
However, I am only critical because I see a very good game here. The art style is unique and the mechanics themselves have the potential to be really solid.
Good job!
