Short update today:
If the game detects you're using a generic controller or Nintendo-like controller, then your experience will be the same as if you're using a Playstation or Xbox Controller.
Essentially, all players that use controllers will share the same layout
At this point, this means that - for controllers - remapping is in BETA status while I work out a long-term solution
For keyboard players, nothing changes! Remapping should work just fine
Hope to see you on the leaderboards!
