Hello, I'm sorry you feel that way but the price increase comes after 2 years of being $5. The price is planned to increase over time as content is added to a minimum of $20.
The recent price increase is to preempt a major content update spree in the coming months including story content. The big content update prompting this price increase has been delayed a bit due to an error with an asset. It should have been fully released over a week ago, but right now it's only partially released with a admittedly buggy version.
Understand buying the game now guarantees updates for the future of which there will be A LOT! I'm sorry it doesn't quite reflect that yet but I promise it will soon. Just caught up in some uncontrollable factors for now.
