A little explanation would be nice. I did not know how to get from HO to CO2, it seemed like i had the same starting molecule as in level 1. I thought maybe you have to split off the hydrogen to make room for carbon? In the last minute i then found a CO Molecule, weirdly moving at the same buttons as my HO molecule. So i figure this is a bug or the game is sadly not finished?
I like the idea tho.
