Matt, in case you’re confused, most of the flak you’re getting is not really about your review, but rather your snarky comment.
You posted about how this mission was very unique. And then when someone else does the same thing, you sarcastically comment on it: “oh wow, it’s almost like a CITY MISSION!?!?! How wild and cray cray and unique.” (Paraphrase)
Honestly, how did you expect people to react to you being a condescending jerk?
I see you've enjoyed my puzzle-y missions (thanks for the support!), so I can tell you my biggest influences are: Haplo, Eshaktaar, Nameless Voice and Nicked.
I gather you're already familiar with Eshaktaar, Nameless Voice and Nicked, but check out Haplo's missions! He's done some very innovative puzzle-y stuff. Among two storms is an especially unique experience, but his whole sinister awakening collection is quite good if you like puzzles (UVI, IC, OTSA, ASF).
Also excellent: Sepulch...
The problem lies with Darkloader, as stated above, it is outdated and no longer supported by any modern FMs.
Some FMs may still function, but many (most?) modern FMs break using DarkLoader. Sometimes in obvious ways (eg crashes) and sometimes in subtle ways that you don’t even realize.
Switch to AngelLoader or FMsel to avoid these issues.
Thanks for your feedback! I agree with you re: that jump. Try as I might, I just couldn't make it any friendlier without breaking the rock puzzle :( If I ever re-master it, I'll definitely try to fix that issue.
