Level ID: 78511101

I started working on this level about a month ago after I told the idea to Splash and he encouraged me to get back into the editor and build it. This is easily my best level yet, and it's the most creative fulfilment I've ever had in this game.
There is a theme to this level, but I feel it's better and more interesting if people try to piece together for themselves what Afterthought is about.

Note that much of this level looks worse in video form due to YouTube file compression. For the full experience, you should play the level yourself, preferably at nighttime :)

Special thanks:
Lena, for your constant support, advice, and feedback. This level wouldn't be anywhere near as good as it is without you!
Splash, for being the reason this level exists at all.
Luar, for giving me a bunch of technical editor advice which helped tremendously.
And the rest of the Alliance (y'all know who you are) for being great friends and people.
