Well done.
The mechanics work well together, when you get the first abilities.
If you polish and juice this up, this could definitely become a good metroidvania.
Some things that didn't work:
- The game feels a little bit slow until you get the first abilities
- The game doesn't really match the theme
- I got stuck when where you the big rocks on the three flying enemies. I pushed the rock all the way to the left and couldn wall jump up :(
