Yumy.io lets you control a black hole that takes in objects and grows larger every minute. To find objects you can take in, explore an urban environment made up of parks, streets and apartment blocks.
There are a myriad of Yumy options for io on the main menu. You can select the one you prefer, but the basic mechanics of Yumy io will remain the same. Click and hold LMB to control a singularity and position your self beneath an object to increase mass.
Play Yumy.io at io Gamers and eat everything! Have fun destroying the city!
