I started playing this during version 0.33, and even in this unfinished state it had more depth and features than many AAA titles. The greatest asset of this game is it's open-ended sandbox style of gameplay. Graphics are mediocre at this juncture, but I expect a lot of optimization come release time. Captain, my hat is off to you.
I have given a 10 rating based on the (qualitative) ratio of version number to game depth and attention to detail evident in design. If for some reason the later versions fail to impress or final release is lacking, I will certainly return and update this review accordingly.
don't download it. don't even look at the download button. i haven't played it, but it is bad news. it clogs your hard drive by porting a bunch of portal/ hl2 content to portal 2, and it installs rad video tools (not necessary, guys!)and even puts some random source code into your steam dir. and get this: you can't even play it when it's done doing all that crap, because steam trys to update the mod, and OF COURSE that never finishes! so here's a spoiler: this stinks.
