Collision detection is bad. You can guess yourself what that means for a game of this type.

Every time you die it goes to some stupid score thing while the level repeats. This is not possible to avoid. Which means that the level where something expands outwards is already expanding when it throws up the pointless score page, and then to adverts meaning that by the time that score page is taken off the expanding object is already going out too far thus restarting the level, thus bringing up the score submission, thus making you fail again.

Also touching something after beating the level also kills you and restarts the level, hint what happened above.

Adding a poorly following ball to a mousemaze game doesn't suddenly make it a better game, there are ways to pull off a mousemaze well, this is not one of them.

I liked this! Simple yet it started getting challenging around level 7 for me. Is level 10 the end? I collected all the stars before the spinning ball got too big but it keeps just going to a high score thing.

Too few things player can do.
