[Challenge/Puzzle] [Hard] The Underground City

Wow, the level was... is awesome. Thank you a lot Dynamite you inspired me to continue the work on my own Moonjourney hehe.
Really, great level!

Spoiler: (click to show/hide)

Go through the yellow keyhole again. There's a secret area above the waterfall in that room.

Found it... that was evil. Very hard to find.

Wow... this was much better than I expected - it had pretty much everything I like in a level: custom graphics, a decent story line, exploration / hidden stuff and coherency. Great work!

Oh, an sge. Parts of the screen spoilered just in case...

What's an SGE?

[faq]?

am i slow? i can't even get the red key... help?

ty i don't know wut made me think i couldn't make that.

[mod]offtopic question removed, answer is in the [faq]. which would have also been findable with the [search]. [/mod]

Finsihed it, very nice level (and tileset to.) I didn't have to have any help except with getting to the blue door... Not to short, but not to long either, very nice length, it was a little bit unclear what you had to do at some points, but this is an exploring level is it not?

Nice tileset. However, whenever I find a level where you can get stuck because you didn't do something you were supposed to do, it ticks me off. It's even worse in this level, because you normally wouldn't notice that, and you'd be running through to dodge the ball shooters. >_<

Now, to do the level over again, because of bad level design...

Since sooo many people are having touble with this level, I will make a video tutorial and put it up on youtube. (Soon) 

I finished the videos!

The quality is kinda bad for some reason, and I didn't have a microphone to record my voice. Hopefully this will help some people 

Yeah..
