Here is 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 you must defend yourself against the unending assault of smiley faces. For every Smiley face that you defeat you will be rewarded with ten points (the high score is automatically saved when you die). Your health drains away when a smiley face is too close to you and when you run out of health the game restarts. Scattered around the environment are health packs which will raise your 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 you will need to continue wandering around the map to find them.
Use the directional pad or the A/B/X/Y buttons to move
Use the touch screen to turn
Use the L or R buttons to shoot
I’m considering this done. Unless someone finds something broken about the game then you shouldn’t expect to see any updates to it until after the competition. I’ve already spent more time on this then I probably should have.
