Rasvyat has released 3 days late, sorry for that, however it is now out, there's currently no in game tutorial, sorry, however the game is now available.
There are currently a lot of bugs however they will be resolved in the coming weeks, there is a multiplayer issue where the player may get stuck on the "Spawning Player" screen on some lobbies, the only real solution currently is to press ALT - F4 to force exit the game and host your own lobby, sorry for any inconvenience.
