Great art and aesthetic. Music is good. Controls feel good. Mechanically its a fairly complete platformer with lots of potential.
Unsure if there was a goal or win condition to this or if its just a sandbox. Either way i had fun jumping around and climb up on things. I'm a fan of climbing and exploration, see a place and trying to get to it. Even without direction, your game provides that so it was a pleasure.
I played with keyboard. Controls felt good, but I had problems timing the jump on enemy to actually trigger my own jump. Maybe I just suck, but it felt like something was off.
