You've done a great job, this is a fun puzzle game! The turn-based system lets you plan out your moves ahead of time and try to be smart about solving the level. On top of the freeze wave, time is also frozen between turns, so you've done more than you said for the theme.
I found the controls a little bit difficult to use. Sometimes I would click on along a diagonal and the path-finding would take me through the robot and immediately lose the level. I think I would have found tapping WASD to move one square at a time a bit easier, but that might just be me.
Overall, nice work :)
