What each player can do here

P1 · Cuphead
  • Plane fight: shoot, drop bombs, and shrink into the mini plane to dodge.
  • IGN suggests the Coffee charm here.
P2 · Mugman
  • Mugman can join or leave at any time. If one of you goes down, the other brings them back by parrying their heart while it is still on screen.

If your skill levels differ: Cuphead and Mugman play the same way, so split by job rather than by character. A fallen player only comes back if the partner parries their heart, so the steadier player should play it safe; a newer player can take the Smoke Bomb charm, which makes you invincible while dodging.
