That's a spicy one.
I'll give you the first two moves, can you figure out the rest? :) First move is [2 squares right], the second move is [2 squares right] again.
PRO TIPs:
1. On the second move, notice that the green slime moves first, so it blocks the other one! That is, the weakest enemies move before the stronger ones, following the order in the Codex!
2. Second pro tip is that traps activate before enemies can move.
3. Third pro tip is that if you step on a fire, it kills the other enemies around it!
Can you beat the level now?
