I love the intro sequence! You rarely see cutscenes in jam games, so it was a welcome surprise.
I played this game with my laptop trackpad, so I had some difficulties scaling the player size. Often times what I do when I'm making a game that requires a mouse wheel, I also include dedicated keyboard keys that do the same thing. Also some text hints in game that say the controls would be nice. I didn't realize I was supposed to use the scroll wheel until I exited fullscreen and read the description.
