Love it so far! I can barely get through Verse 5 and was immediately annihilated the only time I made it to Verse 6.
That said, the first time I cleared Verse 5, I got scared by "This is it" so I backtracked to the previous room, hoping to get to rest, but I couldn't, so when I went to proceed to Verse 6, I just walked endlessly through the void, rather than getting a screen transition. As I recall, the orange bars or light indicating that it was a transition zone weren't there--I just walked into the purple. I had to quit the game and struggle through Verse 5 again to confirm that wasn't supposed to happen.
So basically, if you clear Verse 5, don't go back. Be brave.
