Do you like puzzle games? They you might like this. Don't be fooled though, this isn't really a puzzle game. It is much more than that.

This game tricks you into being an engineer. It starts out all cute with these simple little puzzles, and 10 0hours in you're managing multiple plants, multiple processes, matching inflow with outflow, all while shooting lasers at giant floating pyramid.

I've never really been able to pick up coding, but I have a feeling that this game kind of feels like that. You are given a task and you begin to put together different little tricks that you have learned in order to complete that task. When you find out that your old methods won't work you have to devise new ones. Then you refine your design, improve upon your tweaks, and rework solutions in a more holistic manor to improve efficiency and economy.

Trust me, try the demo and you'll get hooked. You'll make your first solution and be all proud until you see that someone else solved it in half the number of cycles using 1/10 the commands, and you'll spend three hours tinkering until you can match half their success.

I know, it's really hard to explain why this game is so great. If you want a taste, go to www.zachtronicsindustries.com and try out "The Codex of Alchemical Engineering." It is a very similar game (though much cruder than space chem) and you should be able to see what I'm talking about. (While you're at it, if you're really into driving yourself mad, try out "Kohctpyktop.")
