I absolutely loved the zoom-in on the (cute!) character when i collected an object. The desire to see it again kept me going through the bullet screen! I found the difficulty ramped up pretty fast and I'm not a great platform player but I still enjoyed figuring out what sequence of moves would get me past an obstacle.
I appreciated just restating each screen with no lives that would cause a full restart or anything. I thought the music was a bit incongruously calm for a tricky platformer.
The little climbing animation when you hit the side of a platform was a nice touch! Overall great work, congratulations!
