Ooh, good point - I always forget to make the point that the procgen is consistent, rather than random (I'll update the "features" list 😉).
Yeah, that spike is unfortunate - but alas, seemed the lesser of two evils for an overall "okay" procgen seed (psst... the reason it has 20 levels is coz the procgen for levels 25/26 became pretty impossible to complete!)
As for your puzzle - haha... BRILLIANT! 👏
I'm assuming that "rocket jump" is due to me needing to remove the "don't let player.Y < 0" check, due to lack of chars? 😉
If so... here's my replication of that puzzle (spot the extra "life")...
P.S. - It's also possible to "miss" the Holy Grail at the end and fall down to level 21 🤫
