cute short game.
I wish I didn't have to play fullscreen. The text was hard to read because it was so blurry and close up. (now I realize I could've just resized my browser window) Still it would be good to give the option for fullscreen or not.
the character and all the level visuals look really good. I should learn to make particle effects like the ones in your level end portal.
Found it weird that you didn't get squished by the moving platform. If you're with the door you actually teleport above it. You couldn't detach the door either, which could be annoying unless you make it more of a puzzle game and it's more of a game mechanic. Level design was too short to really comment on.
No sound is always very noticeable for me.
Looks nice but gameplay is too short and easy to actually know if it's a fun game or not.
