Hopefully the game natively supports xboxone/360, ds3/4, switch pro out of the box. Steam controller support coming.
Jump: jump/toggle flight/stun cancel
Attack: short range(tap), dash (hold and release with direction)
Special: fireball(short tap) blast (hold and release with direction)
R: resets the current level.
Escape/Pause: open the menu
Default keyboard controls are garbage and designed for me to test move interactions one-handed (xbone controller awkwardly in the other), please feel free to remap them and suggest a default mapping.
wasd : movement
jkl: attack, charge, block
Currently the game is limited to one mode (versus) and is local multiplayer only. I'd be interested to see how it plays through a service like Parsec, but be aware that giving someone access to play a game with you remotely is a security risk.
Please use the forum for bug reports/questions/suggestions.
