Is buying uranium supposed to just give a black screen?
As others have said it's fun and interesting how the different mechanics work. But the chemical reactions forcing you to buy one element at a time is annoying. I only used it a few times. Especially once I got the last primary atom and just idled to victory.
Also the star cost feels like there is a bug somewhere. It was giving me a lot of stars even when it said the next one was orders of magnitude more than my current photons.
