The TOHU game freezes on my system at the same place every time. This occurs a good ways into the game and well past any refund ability. Anyone else?

Also, there is no forum dedicated for TOHU. Can this be addressed?

Refunds aren't limited by time played. Only by how long you've owned the game. Although, GOG's refund system is overloaded right now and they're slow as molasses in January. But you can still request it. As long the the request is received within the time limit, you should be good.

As for the issue you're having, can you give your system specs and where the game is freezing? Maybe someone can help you.

No forum page for the game is possibly an oversight by GOG. So you could contact them about that too.

A response to that contact might be real slow right now, so perhaps start a topic here, similar to this, but make it a question ... that might get noticed sooner.

Maybe a game has to qualify with so many purchases before they make a forum page for it ... or they get enough questions about the game.

Your issue may not be related to the GOG version of the game, so have you checked other game sites etc ... as surely you would not be the only one having the problem.

What about contacting the developer directly.

Going uphill? With crutches?

I recommend two things, first contact GOG about your problem and inform them about the absence of the especific forum for TOHU. And secondly, contact the developers and inform them about the bug, if it's in a specific place they will know how to solve it or will update the game, in any case they will fix the game.
If you want to try to find a solution here, please, post more information, like your specs, system and the exact point where it crash, or post and image with the error, pr crash section, if anyone has the same problem and solve it I'm sure they will try to help!!!
