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

it's fun but I do have some major complaints. 1: the game is SO slow and laggy, it really ruined my experience. 2: you can only hold one element at a time, which is annoying when you make a mistake. 3: the fact that you can't zoom in, makes it very hard to make detailed builds. this may or may not be read, but it was worth a shot.

Great game but is really annoying that at the moment if I'm burning wood (just coz) and it touches the lowest part of the box and I clear the screen (using clear button) and then put some wood down close to where it was it reignites randomly.
