I don't consider this a spoiler, as it was rather obvious once I saw it... The palette goes on the pin under the rag in the paint-by-numbers painting. You don't need to fill the palette with colors first, despite it looking blank in your inventory.
I was right.. I severely dropped my my CPS when I spent 3 septendecillion angels.. In other words, most angel spends don't make sense, and definitely the ones that ask before you spend.
Michael3710 - It's a matter of math. say I'm making 100 units/ sec. Each angel gives me 2% increase (base), so every 50 equals a 100% increase. So with 10,000 angels, my 100 units/sec would become 20,000/s. Trading those 10,000 would make me give up the 200x bonus for having the angels, for a 3x increase of my base... so I would then be making 300/s. Either not a good switch, or like you said, I don't understand how it works. Please use my example to explain where I am wrong.
2 stars if 3+ hearts are missing, 1 star if 2/3 stars are missing, otherwise you get 3 stars. Difficulty level doesn't affect the stars income. Each unlocked achievement (there are 48 of them) gives 1 star.
