I loved the hand-drawn graphics, the script, the characters (the orb spirit was cute!), and the ability to glide after a super jump (which I used a lot while I was playing the game). Final boss was challenging, but once I figured out its weak point and how to dodge its attacks, I was able to beat it in a few tries. I also liked how the player is allowed to change the controls at the start of the game. I initially didn't like how I had to use LShift to crouch, but upon a second playthrough, I changed to the down arrow key and had a much easier time beating the game.
A minor issue I had was that I didn't like how I was not able fire projectiles while I was in mid-air. I also would've liked it if the pressure tile puzzles had letters on them so that I know what word I was spelling out.
It's a pretty solid game overall. Great job on the game!
