Soda Drinker Pro — the game that simulates drinking a soda — is discounted by 50 percent this week to mark one year since its launch.

Normally priced at $4.99, until Jan. 7 it will cost $2.50 to buy the DRM-free Windows PC and Mac version of the game. The full version of the game has more than 100 levels and Oculus Rift support.
