*Watch for control of Simon (I usually look at the candles) after the door. Jump immediately to have the medusa hit spawn above Simon's head level so you can just walk to the rightleft. You need to collect 6 hearts (5 to use the watch and 6th for a holy water throw in stage 6) - you can either collect one from a candle and then get the big heart after the knight.

*You can make the frame rule at this door but it is tight. You need to not do a whip buffer, walk as far to edge of the first platform as you can without falling, then jump, move to the second block on the middle platform, do a jump to have the medusa head spawn higher, hesitate, jump to the next platform, then jump up and backwards to get boosted to the upper platform. Then walk rightleft, and jump to the lowered platform at the door. Keep in mind this saves not a huge amount of time and if you miss you will fall into the pit. Credit evadecpatcha's pb video
