Gameplay

In the game, players need to feed their character to a starving monster at the end of the level. There are 8 levels in each world and 7 worlds in the game. There are also diamonds to collect, but players don't need to get them all to finish a level, yet must collect some to unlock more worlds. If they get 99 diamonds they unlock the X (8th) level in each world.

Competition 5

One of the reasons the newest version is one of the first published by YoYo Games on the YoYo Games Store is because it won 1st place in the 5th YoYo Games competition. The theme for the competition was to design a handheld game. Jesse Venbrux also won 1st place in the 1st YoYo Games competition with Frozzd, which uses a different game engine, also based on the 360° gravity system.

Differences

The original game is similar to the new one, but it is shorter and has a different scoring system. All differences are listed here:

• There are only five worlds, not 7.
• World 3 was added to the newest version as "exploding planet world".
• World 4 in the newest version was world 3 in the original version.
• The yellow world (4 or 5 depending on which game) was "orb world" in the original, but is rotating planet world in the newest one.
• World 6 was added to the newest version as "orb world", but it is red, not yellow.
• World 5 in the original one is world 7 in the newer one.
• There was a tutorial world in the original.
• There was no level select in the original, just world select on a carousel. Players had to beat level 1-1 to get to 1-2 and so forth, but worlds were still unlocked with diamonds.
• Diamonds reappeared in the original, so players could just play level 1 and beat the whole game.
• The player was taller in the original.
• The music was shorter in the original.
• There was only one X level in the original. It included the monsters the players were feeding, shooting at players, who eventually escape in a rocket.
• Level design, but world 2 is pretty much the same in both versions.
• The original is only for PC
• The original is free
