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.
