To be honest, I am a bit confused on what to do, it seems that there are objectives to do before the time runs out? I realised you can "shoot" the cubes in the "fps"-like section, but that didn't seem to trigger anything, and I am still unsure what to do in the section with the green, circling block, except slowly move into it? Nothing happened when I reached it, though.
I do like the aesthetics of the starting splash, and the way the cube moves on it, though. I think that alone could be expanded upon, maybe into a skill/race/avoidance game?
