Tasty Planet: Back for Seconds

Tasty Planet: Back for Seconds is a game played by Markiplier.

Game Information
The main objective of the game is to get to the size specified by the level. This is done by eating entities that are smaller than the Grey Goo, and avoiding those that would harm it, such as dinosaurs, bacteria and samurai. However, touching a damaging item only removes a small bit of matter for the grey goo, and there's a limit on how much is removed, so on Casual mode, it's impossible to lose the game. Also, the vast majority of the harmful object ignore the grey goo, and only a few, like the bambiraptor, actively pursue it, and nothing in the game can move faster than the grey goo. The level is complete when the Grey Goo has reached the required size or otherwise fulfilled the stage requirements (such as, perhaps, eating a set number of eggs or mummies). On the timed levels, players can also try to achieve the "Medals" for each level by completing the level under a certain time limit, which can be found on the level select menu by mousing over the chosen level.
