Great game, although the tutorial could be confusing for less geeky players. Or maybe that's what the video's for; I didn't watch it (necessitating a YouTube video to play a downloadable game just strikes me as odd). This is definitely one of the better programming games I've played, and I like how you used the Periodic Table with it.

I tried the demo with ubuntu 12.04 and windows 7, both install with easy and runs smoth. It's a great puzzle game, that makes me imagine how good it will be for some fun with chemical class at school.

Will the update come to desura eventually? Having the "Update released" message ingame makes me nervous.

Trying to play Spacechem on a fresh install of Ubuntu 11.10 I had the following issue: The game didn't started trhough Desura and starting by the console I had the following output:

"The assembly mscorlib.dll was not found or could not be loaded.
It should have been installed in the `/usr/lib/mono/2.0/mscorlib.dll' directory."

Looking at "/usr/lib/mono" I found out that only the folder 4.0 was there, so, long story short I resolved this problem installing:

libmono2.0-cil
libmono-winforms2.0-cil
libsdl-image1.2
libsdl-mixer1.2
xclip

(The dependencies were satisfied automatically)

And edited the file "~/desura/common/spacechem/spacechem-launcher.sh"

changing the line "./mono SpaceChem.exe" to "mono SpaceChem"

I'm not sure if this is the right place to post this but I hope it helps, because it was the first place I looked for support, by the way, thanks to everyone that put answers here or in the forums, it really makes the difference guys >D

This issue is fixed now, at least it works here. :)
Please report Linux game problems in the "Application Linux" forum: Indiedb.com

Thank you so much. Installing the dependencies fixed it. It should be noted that you no longer need to edit spacechem-launcher.sh because the most recent update has already changed it.

I'm at a point in this game where I can play this for very long amounts of time. This is a good thing. I get my next puzzle, close the game in disgust ("HTF am I supposed to do that!?!") then proceed to spend the next few hours or days thinking about how to solve the puzzle. It's a game you keep playing, even when you're not playing. Then it gets worse, you finally find a solution, but it seem inelegant. You are using too many components, it's taking way too many cycles. And the process begins again…
