Kamek's Volcano (Savestateless, Checkpointless, Damageless)

Stars are at these times:

0:00 - Act I - Anomalous Materials
1:13 - Act II - Magma Chamber
2:21 - Act III - Ascent
3:14 - Finale (Checkpointless, Damageless)
6:50 - Encore (Checkpointless, Damageless)

Really cool little hack, the first 3 acts aren't anything special but the Kamek fights are the main event here and where you'll spend the majority of your time in this hack and they're a blast to play. I challenged myself to beat both of them damageless and without the checkpoint (both halves of the fight done in one go). Finale wasn't too tough but Encore was quite challenging. It took me around 3 hours of attempts to finally get a damageless completion. Before that, I had beaten it 3 times taking only one damage in the 2nd half and one or two other times taking damage in both halves. Got slightly tilted at times but nothing major and overall really enjoyed my time here.
