This one is quite hard but elegantly designed. The “cell freezing” mechanic is unintuitive, I wonder what theme/skin could be used to make it easier to understand.

Surprisingly tricky for such a simple mechanic. Very nice.

Great game. The core mechanic seems gimmicky at first, but the game proves that it actually carries quite far. The amount and consistently high quality of the levels and  the demanding, but  super satisfying difficulty curve make this game a real treat. 
 

The twist to the rules was really clever and intriguing.
