Rather good
Hi,
This game is rather good.
One point of frustration though: the things are a little bit too small to click. Take for example the R button: if you press it with the mouse it takes a few tries before it works, because not every area of the button is clickable. But now take into account that the draggable jumpy barriers look like 10 pixels thick but only respond to the mouse at 2 pixels thick AND that the moving molecules are also only clickable at a very small zone, and you see some frustration!
Still very good for the rest! I gave up at level 44 though...
