Me: 23 malignant cells + empathy + dagger... Opponent: 3 pharaohs and 10 scarabs + Poisioned (8) + delay shield + empathy + some healing weapon... I won with just 2 hp left, lucky me :3
Finished Level 35 without using all of the items:
Magic Orb @ A11
Light Bulb @ B12
Food @ G11
Cannon (Facing Right) @ H10
Cannon (Facing Right) @ J10
Mirror (Facing the Upper-Right) @ L8
Solar Panel @ L12
Then hold the Mirror facing the Bottom-Left over the Target (The thing that looks like an atom) and try to direct the laser beam into the Laser Feeder @ H7. It's probably a glitch but it still works :)
