Sorry for neglecting this, but stuff has been happening IRL. Among other things, I'm hard at work trying to make this whole game development thing a legit job for myself. As for the source-code release, I'm not even going to "promise" that. Not yet sure about the financial side, but I'm sure as hell the code is messy and almost 100% undocumented. Custom homebrew engine and custom everything. The tools I could've tidied up a bit, but I just never got around to do it. Sorry about that. I won't even pretend that the lack of motivation doesn't come from the fact that I have nothing to gain by doing this (as opposed to some other stuff that's eating away my time and brainpower these days). Though I didn't promise it, I'll still feel bad if I just wander off, so I'm going to look around my hard drive right now, and if I find any useful builds of the tools I used, I'll post them here, along with at least some instructions. Stay tuned.

EDIT: Ok, here's what I can offer for now:

• SMLED 2.5 (tilemap editor, written using .NET, works on Windows, tested previous versions on Mono/Linux years ago, not sure if it works anymore)
• GFlow (flow map editor, Java JAR, should work anywhere)

PLEASE REMEMBER these were never meant to be released or used by anyone else but me, so I'm putting them here without absolutely any guarantees. You should also adjust your expectations regarding user-friendliness and stability. Smled is more-or-less ok, but GFlow is a horrible one-off tool.

So, now I'll try to piece together some sort of a guide and make it my next post here.
