Ah, this takes me back to the very first yeti game (this being essentially a clone). That was better.
I concur With TheLazyWierdo!
This game is rather simple. The art is cute, as well. However, I believe this game might be too simple. The huge concentration on simplicity may make this game dull. The only difficult thing is getting the timing right. My suggestion to you is to make this game more competitive. Add hi-score functionality and objects that will propel the mouse forward (such as springs and jetpacks) and objects that will stop the mouse from moving any further (such as mousetraps). That way, you may make this game build up a competitive atmosphere.
It's ok. If you want anyone to play it more than once then you need an upgrade system. New bats, extra force, special items, ect... Also the mouse's squeaking gets annoying after once
