Rainbogeddon is an action-platformer game released on February 2, 2012. In the game, the player controls a grey creature, with the goal of collect all pills while dodging enemies. The grey creature is always moving, with no way to stop it except running into walls. This game has the same basic concept and idea of Pac-Man. The player only has one life, and can collect power ups that appear randomly throughout the levels.
When a player touches an enemy, it will die unless they have a power up; it counts as a second life. In this case, they will lose their power up and become invincible for a few seconds. Each level has a certain amount of pills needed to complete the level, but if the player dies, they will have to start the level over.
Rainbogeddon has forty levels. In each level, the grey creatures have to collect all pills before proceeding to the next level. Enemies, which respawn once killed, will try to hinder the grey creatures. Power ups can be obtained and used for destroying enemies. Collecting several of one power up will strengthen it, increasing a certain part of it (e.g: A strengthened drill will drill faster than a basic drill).
Father jellies - a green frog's head that animates like jello which will randomly wander around the maze until close enough to follow player, has no special abilities, and is the easiest enemy to escape from in the game.
Fish - a pink fish-type creature that moves slower than the Father Jelly but will follow the player more, and can shoot the player when looking at it directly.
Blue spheres - a blue ball with eyes that is like the father jelly, but moves faster, can home in on players more easily, and appears smarter because of how it tends to corner players.
Elite blue spheres - a blue Sphere with a mustache and hat, which doesn't appear to have any different personality that the Normal Blue Spheres.
Worms - a red worm with many segments that can kill the player with any of them, but only dies when shot a number of times in the head. Homes in on player easily.
Temper monsters - Starts out as what looks like a yellow Thwomp from the Mario Series, that behaves like a Normal Blue Sphere that doesn't home in on the player as well. When it fails to catch him/her it will get angry and turn into a green beast that is better at tracking and is faster.
3-eyed spheres - a red eight-legged creature that can send out a Probe to follow the player on sight. The Probes follow the player well, but the 3-Eyed Sphere alone doesn't.
Squids - a red lightbulb that will flash on and beep when it sees the player. When the beeping is active, all the other enemies will home in on the player, no matter what default personality it has.
Spike-haired blobs - a yellow spiky head blob that's like a Elite Blue Sphere, but much faster.
Black cats - a black cat's head that acts like a Spike Haired Blob, only they travel in packs.
Fuzzy spheres - Fuzzy green spheres that become angry at the sight of the player, turning red and becoming stationary.
Waste monsters - Ice cream shaped monsters that leave waste near a location that is heavily visited.
Baby jellies - Small male and female jellies that follow the mother jelly, being poor at chasing the player
Power Ups are objects spawned into level in Rainbogeddon. They are spawned into help the player, and can be used to kill enemies or for other uses. They can be strengthened by picking up several of the same power up.
As seen in the preview picture, pills were means to be larger. When the final release of Rainbogeddon came, pills had there size decreased. The decrease in size of pills may have been done as to not distract the player.
