This game can be quite cruel to you as well if you don't wise up in time as well.
You can collect trinkets throughout the levels that unlock songs for the game. Each level also has a name for it.
One of the levels is called "A reward for the reckless" I see a moving platform that can allow you to get this trinket, but can only start moving when you initate it behind this wall, the only way to get pass it is to go through several other difficult levels.
The next level along the way is called "Shenanigans"
The next level after that level is called "Deception"
After passing several more difficult levels named similarly, I initiate the platform, and go back through all those difficult levels back to "A reward for the reckless" only, the level reset as I left the area and the platform was stuck again. And to progress through the game I had to go past all the same challenges again and ignore that platform.
All in all, I had do complete roughly 4 challenging levels 3 times, as opposed to one, and I got no trinket in the end.
Apparently You can actually get this trinket, but it involves purposefully missing all checkpoints (meaning doing all those levels without dying even once), keeping the one for that room and killing yourself on the spikes, spawning at the bottom
