Minecraft creator Markus "Notch" Persson unveiled Drop, a free Unity game available to play now, the developer revealed on his Twitter account.

According to Notch, the game was mainly inspired by a section of ceiling in his apartment, as well as Fez's ending and Super Hexagon.

Gameplay consists of gamers typing in the corresponding blinking letters on the screen and pressing space or enter to advance. Bonus points are awarded if more than four letters are entered at a time. The game speeds up if the wrong letter is entered and it's game over if a letter leaves the screen.

According to Notch's Twitter, he shared Drop's code with game developer Mike Bithell, the creator of Thomas Was Alone, who then built an Oculus Rift version of the game.
