Price increase on September 21st
As announced forever ago in the Early Access notes, the price of the game will go up slightly to reflect all the content and regular updates that were added during the games Early Access. The price will go up on September 21st, which is a bit before the release of v1.0
Why is it going up before the release of v1.0? To be frank, it's because otherwise I'd mess up the sales calendar for the rest of the year. I want to keep the option open to eventually enter some of the usual seasonal sales, and increasing the price on v1.0 launch day would mess up the timings, as price changes also comes with a temporary price freeze.

If anyone out there hasn't bought this game for $2.99 yet, now's a good time before the price increase.
