Hi, sorry we didn't answer right away. We have temporarily lost access to the developer's page.
It's not because of the monitor that crashes occur. The fact is that the game was in development and to attract attention, we made it a free beta. The release was supposed to take place on December 15. Therefore, we have frozen all the old free versions.
If we didn't freeze them, the players weren't buying it in the Steam to support us, but were downloading this free mega bug version.
In the end, they scolded us for a bunch of bugs...
