I didnt really understand the plot or where this was going but I entertained myself quite a bit by just capturing all the blue cubes, and then sending away all the red cubes and then trying to capture the black ones and then I was sent to a green world and had to restart.
All in all the gameplay is interesting and eve whitout knowing anything just the challenge of having to keep the cursor on the objects felt fun so I'm sure that if you expand this it would make for quite an interesting game. Graphics were good, sound as well.
