At level 2, you can use Ruggedness + Improve on the first turn, then Assassin + Force on the second turn to more than double your strength without a drawback. At level 4, use Chameleon + Beast-Form first to more than quadruple your strength and improve your accuracy, all while making you effectively invulnerable while you set up. At level 5, Improve + Ruggedness, then Beast-Form + Demon-Form, then Assassin + Force allows you to reach incredible attributes. I was holding two blunt weapons, and I could easily hit for 350-450 damage at 95% accuracy for both strikes on both hands. This translates into a dependable ~400 damage hit four times per turn, starting on the fourth turn, since what should be six turns of setup is, thanks to this bug, only three turns of setup, and the effects last much longer. I'm not sure what the setup is for Wildcat or Human, but I'm sure there are exploits for this bug there too.
If you click between two buttons, you can activate two adjacent powers at once. I've only played with the Mutant class, but it is totally gamebreaking.
The fuel thing isn't that big of a deal, although it is annoying. I just wasted an hour on a game that actually gets easier as it progresses before realizing it was utterly pointless, because it was just that fun and inventive. Brilliant.
5/5
This game has a good idea, but needs to be reworked a little. It feels a little underdeveloped, not that it lacks polish, but some of the design choices are a little wonky.
-1 for unoriginality and poor implementation of said unorignal concept
-1 for poor graphics.
-1 for spamming me with flash errors.
-1 for the description informing me that this game was fun.
-1 because you're adopted.
1/5
Also, just don't advance on the world map and you can fight the first boss ad infinitum, getting a boatload of exp and cash every time. Not enough to really do all that much, but it helps you to gain four or five levels.
