It's $19.99 on Steam now. If you are lucky and it shows up in your discovery queue, you have roughly 1 to 1.5 hours to buy it at 10% off for around $17.99. I had intended to do this, but played the free game demo version for a half hour first. Something went wrong with a page reload, and the discount disappeared. I bought the game anyways. Though it is disappointing that the glitch cost $2. It's not a lot, and I am still happy to support the developer. Edit: Fixed typos.
