Yes, I agree that object placement isn't very good. I never did a Sonic fangame before, so I was kinda limited with the objects that were avaiable on the engine (and that is Sonic Revival's Engine by Chaos Rush btw), so for the most part I spread the objects throught the level.
I thought that the exploration levels would be the one that most people would hate, because Sonic it's more about action that exploration. I only did them, because it's not easy to transform a website layout, where you go from A to B, so this stages would spent more time to complete and didn't have to worry about paths.
It's true that I did much of the work my myself, but I also have help from other people (check the credits =D), like .dll handling and some progaming algoritims were made by two good friends of mine (Megas Bahamut Alchemist and Nitronix/Jeferson).

I'm glad that most people like it, and sorry for me to take so much time to anwser. Just after the release, an awful virus stroke my PC =(
I wanted to work in a patch that fixed some of the problems that you mencioned, but GM6 has some problem to with virus...
Also, I noticed that Tssz News mencioned Sonic Web Access, and that made me very happy, I never predicted that a "one year project" would made this much sucess. I just didn't like that they call me Neo Nightmare (it's the nick name that I use here, but I'm really know as Himistu no Nazo of [lack of creativy] Nezo the Hedgehog) XD
Since the International community liked the project, I will think on releasing Internation levels as DLC. Would you like a SFGHQ level? XD
Anyway, as far as DLC goes, I will only think about it in a few months... SWA to I want to focus on school for now.
(also, can't awser to PMs, I don't have 10 post yet)
