Pretty cool that you went for a metroidvania! Controls feel nice and I like the graphics. Unfortunately I think the game is a little too difficult. Some of the enemy hitboxes are too big, and there are some parts where you have to make really precise jumps or have to take damage to proceed.

I definitely didn't explain the mechanics of the game too well. When my friends played it blindly they didn't know they could shoot up or when they're in the air they could shoot down so for the full release I plan on adding a pretty thorough tutorial. I also plan on flushing out the difficulty a bit more because like Vimlark said in his tips for game jams "make it easy." I went for the dark souls of MetroidVanias and it should've been toned down a little haha.
