I am hooked on this game. Grim Joggers is somewhat disturbing and downright brutal at times-especially when you are running through the battlefield and limbs are flying-but it is easily one of the most entertaining platformer games I have played.
The charm of Grim Joggers comes with its retro interface. The little joggers all graphically look like they are somewhere between the NES and the SNES, and the sound effects and upbeat theme music really set the mood well.
Unless you're driven insane by the idea of playing another endless runner, you should definitely take the time to enjoy Grim Joggers, if only to experience the random madness of trying to keep everyone alive as long as possible.
