I beat the game. But I am not sure how many levels I might have accidentally cheesed through pushing multiple blocks at once. Or certain blocks not going their full distance and getting caught on corner collisions. Perhaps that was intended, or accounted for in level design. I do enjoy solving puzzles. So that was fun.
I do not think I fully understand the intention behind the angry red circles. Going back it looks like they prevent you from pushing any blocks they are turning red. During my initial playthrough I just went around and turned them all off. So to me they felt useless or pointless. Perhaps I missed something about them.
Now what I really love is a wacky use of a core mechanic for something unexpected. And I was pleasantly surprised to be kicking ice blocks in a boss battle at the end there. I did read the description about there being a boss. But I forgot or dismissed it apparently. I suppose I was more focused on crushin' some puzzles.
Overall, I enjoyed my time here. Keep up the good work.
