Okay, I've played it last evening! I'm about 50/50 on the good and bad points. I played it through and it was pretty good. The maze wasn't even a problem... sure it took at least 10 minutes, but I found the right warps with tries and errors. I found a wallswim in there, where the maze becomes black and green, an obvious warp or design problem. Many voids also, noticeably in the trees area.
What bothered me the most, it's when you manage to find an item, power-up or key, and suddenly you lose it without any explanation at all. The hologram, the purple key... Also, in the first cave, the man says you need the Climb, but what he should say is "you need the umbrella"! I saved, and couldn't go back out since there are no-climb walls.
I didn't like the ending, but it's just my own view ;) ...yes, I tried to save them, grrrr >)
Also, after picking the wrong choice, I was sent back to the entrance of the area (where you enter the white thing), instead of the last save point. Some spots are pretty hard, so I didn't appreciate having to do it again. And the "lol" block was just strange imo.
With some small corrections, this level is a must-play! Possibly your best one yet. Sorry if my review sounds harsh... like Yohji said, there's a lot of work put in there, and overall I had a good time playing it through!
Liked it a lot. Design is better than in Transferal and Supreme Sanktoh (haven't played other levels yet), though it still suffers from same problems in smaller amounts.
Some bugs:
1) Folder name "Level - Author" instead of "Author - Level"
2) x988y995, x988y996 - voids to left & right
3) x996y1027 - that save point should be in screen x996y1026, before the challenge
4) x1000y1022 - spikes at x1y2 shouldn't exist
5) x1033y1007 - autosave shift used instead of non-autosave shift or win tile
6) x993y1000 - climbable invisible wall on the left side
7) x1031y1019 - save point needed after the challenge, before unexpected death from spikes in the next screen
I managed to get the purple key but didn't have the blue one, so I ended up jumping on the blue locks and then fell into a void to the right. I checked previous areas armed with run & climb powerups and couldn't find the blue key; so I'm stuck. Eh!
You are supposed to jump on blue locks, just don't go into the void :)
