This game has been really cool! I love the atmosphere, audio and the puzzle format. H.A.I is really fun <3
It would be nice if the player could pull up the messages describing the new atoms to re-read after closing them. And maybe have the messages point out the colour change that defines the new atoms?
I may have ran into a bug. It seemed one of the levels was immediately completed upon loading it. This one here:
Overall, amazing game!
