Damn. I wonder how long the gameplay is in total. I know it would vary. (Especially for someone like me who misses an extra comma or something benign for like 3 days.)

Well it's a puzzle game and a sandbox and an MMO so I'm not really sure if you can win.
The puzzles are crazy hard and take totally random amounts of time to crack.
The sandbox lets you go off and do random stuff.
A system can only sys.init 4 times (level 0,1,2,3,4).
I've been playing a while and am barely level 2 after automating T1 stuff.
The game progress comes in bursts you'll be stuck on something and make a breakthrough.
The learning curve walls are very high.
