Hey, 

First of all, let me apologize for the mistake we made.

We changed the price with the intention that NEW buyers would pay the increased price. It made sense to increase the price, as we added a lot of content when we released the final version. We didn't know that EXISTING buyers would not be able to download the updates unless they bought them again. Itch is a bit confusing when it comes to this, and also we didn't get any notifications from Itch about your comments. We realized the mistake when someone reported it on our Discords. 

Now, we have reverted the prices to the old ones, and have hidden this game page from new Buyers, so the old buyers should still be able to get their updates at the old prices and for the New Buyers, we created a new page, with the new prices. 

Again, we apologize for the mistake and rest assured, we never intended to scam anyone.
