Sadly the "fixes" for the broken medals no longer seem to work, but if you are not achievement hunting then this is still a pretty fun game. It does indeed lag as you progress.
Colorful characters and fun music, plus some interesting puzzles make this an okay experience.

Attention guys n gals, for the broken medals, try these:

1- Mook Munchies: Feed EXACTLY 50 mooks. This can be easily done by replaying the first level over and over again...

2- Simply Delicious: Replay level 1 from level select.

The game: Lags a lot, broken medals, somewhat fun, 3/5.

"Mook Munchies" is broken from what I can tell, but to get the medal "Simply Delicious!" you have to go to the level select, and choose to play level 1 from there, beat that level again, and then the medal awards. So you should be able to obtain "Simply Delicious" by doing this.

Also this game lags up like all hell. It's basically not even playable on Firefox due to the extreme lag. Even on Chrome the performance is still bad, but at least somewhat playable.

Rediscovered this game. Completed the game and found out that the "Mook Munchies" and "Simply Delicious!" Medals are both broken. Received the medals beyond those at least.

I like the idea of this game. Puts a little twist on the balance game. But the medals don't work.
