Thanks a lot for the appreciation! 192 is a nice score, I've done something like 250 (I don't remember exaclty the number)
1) That's really clever, I will try to make it work!
2) The rotation was as you described at the very beginning, but after a few playtests I decide to switch because it was really slow. In addition to that giving player less options to choose from could be better in order to improve the challenge and the decision making process.
3) It's not possible right now but I will figure out a way to add a mechanic of this type. The main issue with this game was finding a way to make the player lose.
At the beginning there was the classic game over when a block crossed the line, but I think it would have been too unfair and against what makes physics fun, so I implemented this experimental life system. (It definetely needs more balancing)
Anyway really thanks for this feedback, I love to talk about game design like this!
