Looks and plays great! Using X (on keyboard) to interact was a bit of a strange choice. Are you using a QWERTY keyboard? E to interact is more common in PC games, I find.
This game looked so polished that I was sad it was so short! Having an end game screen instead of just closing/crashing the game would be a better ending (or at least go back to the main menu). I wish there were more enemies than just the one, as well. But the storyline was cute, you implemented the graphics and animations very well, and I was excited to play it! Nice work!
