This game is far too luck dependent. And without a "good" AI for the hired help, some waves can be nearly impossible due to having to take care of your "weak spots" yourself.
Hate games that discriminate completely against people using mousepads. The bouncing balls stage is IMPOSSIBLE without the speed clicking you can do with a real mouse.
2/5 - Fun game, but several levels are too dependent on being very fast at click+drag. Tried first on my laptop mousepad, and couldn't even complete the 11th, 18th, or 19th stages no matter what I did. Plugged in my mouse, and still was a pain because of timing issues.
Puzzles don't make much sense - required looking at walkthrough to ever get all the way through.
Worst was the final number puzzle, which has NO clue to "invert" the letters you just used.
