To be honest, I don't know if I understood the game, I just created some planets and made them bigger and had fun :p.
But for an honest review, it actually surprised me the amount of things the effects can "affect" how the game looks at the end, the art overall is great, but there is something on the mouse and the way you make the planets bigger or smaller, that it just hits...
Really great use of effects, music, and sfx, the gameplay was entertaining (but to be honest I think I got stuck haha)
