Cubedere Simulator is a game created by Jackboog21.


You are Cubedere-chan, a black dot (by default), that wants Cubepai but Osana Cubimi wants him too, so you need to kill Osana.


On the title screen, you can customize Cubedere-chan to be Black, Grey, Orange, or a lighter Grey. If you don't change her, she'll be black by default.

When you start playing the game you can see Cubedere-chan, Cubepai and Osana, you will win the game if you kill Osana, simply done by running into her. Once killed she'll be tinted red.


As of now, only 2 DLC has been released.

Many Colors

The Many Colors expansion was released on April 15th 2017. It added 6 new colors for Cubedere-chan.

New Foe

The New Fore expansion was released on April 1st, 2018. It added a new rival Cubegami Saikou.

If Cubegami is killed, she will turn brown.

If the Many Colors pack is also installed, Cubegami's light blue can be selected for Cubedere-chan.
