Wow, this is really good! A lot of fun, the design of the characters is really well done and the overall gameplay is very enjoyable!
Really, the only complaint I have is that on my first run, I got caught on the level geometry (right at the corner of the platform) like this, but lets face it: stuff like that can even happen in professional games that got through a lot of testing.
Amazing work, especially for a one-week beginner jam!
