There's no clear objective to this game? I guess you have to keep clicking the green tube in the bottom right-hand corner and it spins faster? While also filling up the squares with stones?

You need to make the objective of the game clear and have an actually dynamic to it. If it really is just clicking the tube, you need to add more to it. The spinning doesn't even slow down if you stop clicking it.

If this is supposed to be a puzzle game, then you did a very bad job, because I wasn't able to get past the first screen.
