Oh, yeas, another "click and erase" puzzle.. so, click this large group OH MY GOD the world is falling! the boundary of physics are broken! ... unexpected. a bit difficult to complete (maybe add 3 second every group erased, shuffle took me precious time) but really original and fun. 4/5
Pretty game. Some ideas for you:
1) something unlockable , based on failed attempts ("finish the game without fail, unlock the superhyper suit").
2) a fail count on the menu, so you can choose easily a level to lower the fail amount.
3) specify in tutorial that spikes and chains kill you, and your goal is to throw out the cube.
OVERALL: 3/5
waaaait... you forgot one command. if you are the maker of this game, why you haven't wrote that shift make you run? 3 commands are easy to remember...
I fixed it now!, it should play smooth.
