If you reopen the game and press start, you can fight a harder version of madhouse right out the gate!
Also as a side note from a dev, reply with the turn count you get! Always love to see how far people can optimise each fight
Oooh neat! I've just beaten the harder version of him and it took 35 turns due to me rolling 2 1s thrice therefore basically killing Jamie with Recoil Damage xD
first time, I got 36, second try, 26
