Lacks testing...
By playing this game I can tell you haven't had too much experience with Mouse Avoider games, this is because you took no method to fix the stupid cheat everyone uses where you hold left-mouse thorughout the game.
There are plenty of simple methods front-page Mouse Avoider games used to use, mainly one where they script in that where if you click it makes you replay the level.
Also, the game lacks interesting context, pretty basic levels and really crappy platforms which are all clearly made the same and just slapped on top.
So you get a five, not bad. It's not that good, but not bad either.
