Cool idea but wears thin fast This game has a cool idea with gameplay based on chemical reactions. Unfortunately it really isn't able to capitalize on this, as there really isn't much to do once you make your first 15 reactions. The shallowness meant that I got bored within 30 minutes. Add on that there really isn't an end goal and the game doesn't really have the graphics to achieve what it's trying to do, and you have a mediocre sandbox game which really should have been better. - Michael

i didnt like the vague design of the elements. for dumb ppl like me id prefer a little tiny hint tutorial or some thing like it. its so interesting and educational. i'd reccommend to my friends but its looks a little primitive
