Great work! This plays a lot like an actually published game I bought made by another indie developer, and the fact that you did it during a game jam is impressive! My biggest piece of feedback if you decide to continue development is that you should make the maps bigger. The characters are so fast that it feels like a shame to confine them to such a small space. Also, the items are not very balanced, but I wasn't expecting any different given the timeframe. Well done!
