Ok, the game is nice and addictive, and reminds me of Cookie Clicker.
Couple points where the curve is toosteep though.
The knowledge board. Until you get to Chlorine, getting the 15% is not very hard, just needs a bit of time. Then, you get to Boron, which, for it's FIRST UPGRADE requires a whooping 3.000.000.000 atoms !!!! Which is even more than the LAST upgrade for Fluor !!! Might wanna rethink a bit the way the numers scale.
The other one is the 75.000.000.000 atoms in stock. For a level 6 quest, I feel that it's a little bit too grindy, and requires a lot of stocking space.
Nice game, but if you make a very long game, make sure that the music is eiter very long, or has a good loop
