From GameBrew - a wiki dedicated to Video Game Homebrew.
A port/remake of Cherophobe for DS.
Like its original Wii/PC version, it has been made for the GBAtemp Homebrew Bounty.
Cherophobe is an original FPS in which player must defend against the unending assault of smiley faces.
For every Smiley face that defeated it will be rewarded with ten points (the high score is automatically saved when die). Health drains away when a smiley face is too close to you and when run out of health the game restarts.
Scattered around the environment are health packs which will raise health. There are also boxes containing additional ammo.
Like the smiley faces the health packs and ammunition will infinity re spawn but always in random places that are out of view so player will need to continue wandering around the map to find them.
D-pad or ABXY - move
