I think making games is like making bread. The bigger the dough is, the more time it needs in the oven. In my opinion, this bread is huge, and looks really promising, it just needs a bit more time in the oven.
What I mean is, the game is awesome, it looks good, sounds good and has plenty of mechanics that make it really entretaining to play, but every of them could be a bit more polished, by things like adding coyote time to the platformer or making the boss special attack a bit slower.
Sorry if I was a bit mean, I think the game's really good and has a bright future, but as I understood the idea was to keep working on it, I thought I could give a little more feedback. <3
