Yeah you are right, the basic mechanisms comes form Sokoban and the pipe games. I dont know why I skipped them as refference from the game description. Now I fixed it :)
The block rotating device is a good idea, I'll figure out something today.
For pushing block besied each other, I made a reset mechanism for all puzzles. But also want to make an Undo Last step feature, but that have some problematic technical part, what I have to figure out before implementing. :)
And thank you for the comments Blitz! As soon the game have rotating platform, I'll inform you :D
