Point and click puzzler, Tetrobot and Co. has released an in-game editor with Steam Workshop integration, allowing players to easily build, share and play custom levels.
In this game, the player solves puzzles based on blocks reactions. Each blocks of the same matter will stick together while other blocks interactions and reactions will allow you to take the best from every situations.
A group of beta testers have already crafted 77 levels, available immediately in the Tetrobot Workshop.
Or, if you wish to create your own custom levels, the developers have posted a few official Steam Guides to help get started.
