Found some bugs, like the sun only being able to drop one sun stone at a time and time manipulation only applying after you buy an upgrade after starting over, but the game is overall pretty good.
Thanks for reporting the bug! I have fixed the first bug - I've tested and multiple sun fragments can drop now! :)
I couldn't replicate the second bug. Time manipulating when upgraded immediately starts making the countdown faster. I will continue to monitor though, thanks for playing!
