If you go into this game expecting a nice little "gotta go fast" kind of platformer, you'll probably be stumped like I was at first. Why aren't there more rooms? What am I supposed to do next? Who am I anyway?
I'd say EMUUROM is more akin to a puzzle game than a conventional platformer. The whole point of the game is to figure out how to use the environment to your advantage so you can fully explore the world. When I finally realized what I was supposed to do, I felt like a complete dum-dum because the answer had been staring at me all along. D'oh!
Some of the 'bugs' I found were actually features that I could use to advance. There's also the built-in potential to screw things up, but never badly enough to make the demo unfinishable. (Unless you manage to clip into a wall or something)
I enjoyed the sense of mystery, funky bleep-bloop music and chill atmosphere, and felt like I wanted to know more about these creatures and the world they inhabit. I did feel like the game could use a bit more hand-holding in the beginning, but on the other hand, that might take away from the joy of discovering things on your own. You are, after all, exploring an unknown world!
Pok-- I mean Emex completion rate currently at 91%. Some day I'll figure it out.
All that said, I think my favorite part is the main menu.
EDIT: Emex 101.75% complete! I give this game a 101.75/100 ;)
