characters seem to have different abilities when charged up? a brief explanation of them would be great
when going up a curved ramp, the character in the ball rotates smoothly but then when reaching the floor at the end of the climb the character snaps 90 degress back to standing normally, it's minor but looks off
went through one of those black rings but nothing seemed to change?
other than that, great fundamental gameplay, keep it up!
