On higher difficulty levels, the treadmill's direction changes more frequently. In the strength minigame, Travis must attack or avoid projectiles thrown at him. A button is pressed to punch airborne projectiles, B button is pressed to kick ground projectiles, & by moving the control stick down Travis can duck to avoid hearts tossed at him. If Travis is hit by a heart he will be paralyzed for a brief moment. In higher difficulty levels, more projectiles are thrown, & are thrown at a faster pace. Both minigames start out at 2000 LB, and increase price at each difficulty. Each one has seven difficulty levels.
