I find that this game isn't as fun as it could be for a few reasons.
1) Movement speed is horrendously slow. You can't maneuver very well to get food or even to just evade the zombies.
2) It takes too long to kill the zombies. If movement is going to be slow, then at least you can kill them quickly. But no, you need to rely on luck for barrels.
3) The car is pointless.
I don't like games that rely on luck for no reason. 3 out of 5 for a great concept and nice artwork but the gameplay really does suffer.
Tip for the final level: Die purposely near the first otter, because you can eat your corpse and get to full health, so I would advise eating it after you get the robin.
I thought rating had something to do with Badge of the Day. Perhaps it wasn't rated low enough... The main issue with this game (and all other Bubble Tank games) is that it's just not fun. It doesn't really have the same kind of appeal that other arcade shooters do because the way to win is so repetitive.
@siread, you did a great job with implementing the star rating. it really extends the life of the game because even though i'm at the point where money is no problem and skills are near maxed out, one bad game will screw you over. there is also so much more pressure in the tournaments and the race for the league title, it's actually somewhat exciting. :D
