Stack anything you can get your hands on in this chaotic first-person tower-building game. Go solo or build with friends as you balance wobbly objects and use tools like tape jetpacks to reach ridiculous heights. How tall can you go before it all comes crashing down?
What a Steam playtest is
A playtest is a test build of a game that developers offer before release. On Steam you sign up for testing on the game's page. Whether you get access immediately, or the developer invites you first, is decided by the developer and can change.
