Very nice demo! The story seems quite interesting, it makes me want to know more about this alien civilization. Got a bit lost at first, but I think you did a good job at guiding the player through the maze. 

The game plays very nicely in general with my i5 6300HQ / 16Gb RAM PC, but there's a noticeable performance drop when the yellow bubbles are within sight. It's quite likely that non-web versions will perform better thought, so I wouldn't worry much.

Congrats! :D
