Not a bad game, the music sounds were really good (when I could hear them -__-)
The creatures are full of surprises and each level is like a little adventure. Really fun!
However, the game lacked story-line and with one, it would make a HUGE difference to the general gameplay and overlook of the game. Also, I found myself having to die a few times on Level 3 before I actually had the gunpower to defeat the level, a few other players had this problem too (going by some of the reviews below mine).. I found that quite annoying.
but the rest of the game? Pretty damn sweet.
Due to the lack of storyline and sudden-hardiness, this game only deserves an 8/10, 4/5.
