Really polished game! I like the art and overall presentation. I quite liked the idea of making a choice to pick up abilities, which would in the end result with harder or easier bossfight. But I'm going to be honest, I couldn't make it to the bossfight. The platforming feels really tight, platforms are either very close or far apart and in the end it lead to frustration on my part. It also largely falls on the fact that I may not be the right audience, as I am not the biggest player of platformers, but I also think that my issues could be mitigated with either shorter levels or checkpoints. Other than that though, the game feels great. Could be expanded into a big and solid metroidvania. There are some very creative ideas in here in general. All in all, a very solid entry, great job!
