Super clean, nicely animated, and pretty UI. It’s really easy to navigate and adds a lot to the overall experience.
The puzzle mechanics are clever with great variety, and I love how each level introduces new challenges. The creative level designs kept me engaged, and the sheer number of levels is impressive, especially considering the time frame!
The character art is also really nice and adds personality to the game.
Being able to undo as much as you like is a fantastic feature. It allowed me to try out different approaches quickly. One suggestion would be to add the ability to hold Z for multiple undoes in a row. It would make the process even smoother.
Great job overall! Really impressive work!
