This was an interesting game with a simple but unique gimmick. You should add more ideas to twist the puzzle and make more impressive moments. Remember that implementing the limitation or theme in a jam is important for experimenting with ideas and give your game more authenticity based on your interpretation of it. 

Unfortunate that the restriction wasn't implemented, but it was a nice little puzzle game with cute art. I think the level itself could be better designed as I never felt that "aha" moment, but instead just went back through explored tiles and got more + points whenever I started to get stuck. Additionally having more levels or even randomly generated ones would be nice!
