well i open the game click posibly every button on the gamepad and still all i see is a white screen
Huh that shouldnt be happening, what platform are you using? When you open the game it should be a white screen but there should read Becalm, and under it there's a couple of symbols/logos. The logos are for a 5 minute game session, infinity and options. Select any of those with the gamepad and press A and it should start.
Ohhhh ok I think I know what the problem is, last weekend I temporarily uploaded an experimental VR version for testing (that had the white screen bug). The itch client probably downloaded that automatically since it was the latest upload, could you try downloading the Becalm_4_Windows.zip that is available on the downloads page? That's the stable, proper Windows 10 edition. Hope that helps :)
