Extremely addicting for a cheap game! A must buy for the puzzle lover and Wii collector.
The only two problems I have with the game:
-The learning curve - After the first two 16 level "labs" which the game is broken up into, the levels get extremely difficult, which will most likely turn off the most casual gamer. If you're into extreme thinking puzzles and are willing to perservere through some mind-benders, then you should love this game.
-The camera angles - They make it extremely difficult when you have to split your blob into two pieces to mix colors, but one coloring station is WAY off the visible screen. You have to zoom WAY out in oder to see otherwise you obviously won't be able to see what you're doing. It takes some getting used to, but eventually can be overcome, since this concept is not seen in the earlier levels.
Overall, if you're not a casual gamer and are willing to think a little bit (I know, what a concept for a game :p ), buy Mercury Meltdown Revolution. You can't go wrong with the amount of gameplay it provides for only $19.99
