When the game was released, it was announced that it would be available for a fee from August 10.
According to the guidelines of Steam Consumer Protection
It was pointed out to us that the base price must be maintained for at least 30 days.
We have been told that the same will be done for free games.
We have decided to apply for a new fee-based system on Monday, August 23.
We apologize for announcing the wrong date.
Free purchasers will still be able to play the game for free after the pay-per-use date.
We will continue to make improvements to make the game easier to play.
We would appreciate your feedback.
