well umh, it seems like the game needs you to press 4 keys at the same time, and i now found out my keyboard only supports up to 2 keys pressed at the same time :D
Yeah, some keyboards are like that. If you have a controller, you can use the bumpers and triggers instead. For a better gaming experience, you may want to look into a mechanical keyboard in the future, though! I like keys with Cherry MX black switches myself.
