The general idea of the game is quite good. Some challenging mouse action..
However...
You overestimated how long it would stay fun so much that it just killed it.
A progress bar would be a good start to make it a bit less overwhelming.
I do think you should have split it up into several episodes or something like that. It is just too much.
