I really enjoyed this! I had a few issues with the space feeling a little tight for the movement required, but nothing that bad.
I also wonder at the people complaining about the boss- it took my first try to understand how he moved and attacked, and I beat him on the second without taking a single hit. Maybe that's more a testament to my own ability than to theirs, but I feel like the declaration that the boss design is "terrible" is going quite a bit too far.
The game has a super cute design, a charming story so far, and a fun little gimmick! I hope that you're continuing to work on it in some capacity, it would be great to see a finished version at some point!
