press green flag 2 times! you can press multiple keys at the same time to have more weapons, but that takes the fun out of it ): keep in mind that this game is VERY BUGGY and is not as realistic as the real game. arrow keys for movement, z for peashooter, x for spread, c for chaser, v for lobber, b for charge, n for roundabout, m for crackshot, a for converge, s for twist-up and if your stuck press d. dont spam or your will only be able to use spread, converge and charge. in the future, i'll add aiming and parrying. if charge isn't aiming for you, in order to aim, move cuphead the direction you want, its kinda tricky if you want your shot to be diagonal tho.
guns that work: peashooter, chaser, crackshot, charge guns that kinda work: spread (right only), converge (right only) twist-up (right only) guns that dont really work but are still usable: lobber (no jumping or bug) roundabout (only works when not facing target, also has no effect on target since it was making it bug, sorry roundabout lovers/users)
