Really awesome job on this! The art and presentation are both just fantastic! I think a more challenging version of this with handcrafted levels would be a lot of fun. Idk if it would've been a good idea, but maybe you could've put every level on a timer so that there's a lose condition adding a bit of difficulty to the game since there wasn't enough time to hand craft levels.
Unfortunately I think I ran into a bug on level 5 when I should've won, the game completely froze and I was unable to continue. Other than that, had a great time with it, nice work!
