A demo is now available on Steam.

Here are the current limitations/notes for the demo:

• Free Play mode is unavailable
• No global leaderboards
• No steam stats/achievements
• The demo period expires after 15 minutes or after level 4 is completed whichever comes first.
• When the demo expires you have a chance to purchase it in-game to continue play without interruption. If you don’t purchase it a black hole will form in the middle of the map and game progress is halted. If the game is then unlocked, progress continues.
• Note that Steam leaderboards and achievements will not become active until the game is restarted.
