Hi everyone!
It seems that some Windows update ruined Reflection of Mine on some machiness. I made a new branch with an application that uses different graphical accelerator. If the game works slowly - It should help. To run the game from this branch you should:
1. In the list of the games in Steam client choose Reflection of Mine and press right mouse button on it;
2. Choose "properties" and go to the "betas";
3. There you should change the "default" branch to the "test" branch and enter the password Reflection2016
4. To be sure that everything is right look at the game title in the list of your steam games - it should change from Reflection of Mine to Reflection of Mine ;
5. You must be sure that the game updated after this (it depends on your steam client options, but by default you should relaunch the steam client).
I'm deeply sorry for this issue and hope that this solution would help!
