Humpsters is a fighting game; however, instead of choosing a character to control, you are required to design your own monster from a set of body parts. After finishing your creation, set it loose upon the other monsters.
The idea is very original; Instead of depending on your skill at button-mashing, you really have to think about how to build your monster because you don't control it. You have to choose carefully where to put each body part, taking into consideration what its function is.
The graphics are very simple, but get the job done. The physics of the game, on the other hand, are very good... or at least good enough for one to enjoy it. There are no blood effects, but the monsters look scary enough to distract you from these shortcomings.
The music is a looping track of rock music (which fits the theme well), but there are no sound effects. It may have been better to include simple sounds, such as grunting when your monsters get hit or other sound effects when body parts get torn off.
All in all, the game is worth the time you will spend playing it, which may not be too much. It will hold your attention for a a short while, but the repetitive gameplay will eventually lose its novelty. This may be the reason why the game itself is too short. A lot more variety in the purpose of the body parts, and a lot more "details" could have made this game better.
