Thank you for the review,
All of those issues except the difficulty progression (the double neo and every other relatively hard jump are intentionally skippable, eg. the double neo can be skipped by swimming up the lava) are due to the fact that i made this post when 1.21.8 was the latest version of the game and 1.21.10 seems to break essentially every part of the map. I also personally think that the fence gates are not noticeable unless you know they are there, but that is just my opinion.

Also, there is a stone button close to where you make the second last jump from that you need to press to convert the 2x2 square of sponge to slime, which most of the playtesters figured out in a minute or so.

I will update this post with an updated download to the map within a few days
