Super pretty game with easy to pick up controls. I will say that I am confused as to where "dimensions" fit in here, maybe I just did not play enough, but to me it just seems like one dimension. And the prerequisite feels a bit shoved in, in my opinion.
I did however have some trouble with the browser version, it tended to crash a lot especially if I died. I don't know if the windows version ran better, but this won't impact my rating ;)
