Very cool idea. I really liked the design and the character was really cute! Also, the puzzles were very readable even in the low resolution and also great implementation of the theme.
The puzzle design was also very interesting. I liked how you needed to freeze the elements in the third level for the bullet to pass.
I did experience a small bug? in the third stage where my character got stuck on the platform and didn't want to unfreeze or move anymore. In any case, very good!
