Cute game! Couple of things I'd say though
- The controls feel a little wonky. And I'd like if I was able to move with WASD
- It seems a little harsh to restart everything when you touch spikes
- An indicator on where the door is after you collect all hearts would be nice
- The music should loop
- I don't really see how it follows the theme
But congrats on your first finished game! The visuals are very cute. I liked it!
