Nice!
A few bugs:
The audio settings reset each time you look at the ascend preview tree
They also reset upon page refresh
The times on the upgrades on the left all shows as '0' after looking at the ascend preview tree, the only way to fix it is to save and refresh
You can press 'yes' on the ascend button even if you can't ascend but it does nothing, and it's unclear when you _actually_ can ascend
EDIT: Thanks for the response! Ascend works when long-pressing the button. That was not clear at all (normal instinct of how to click a button is to short-click it), and the fact that the ascend dialog already works when not even having started the game added to the buggy feel
EDIT2: well it could also have a confirmation yes/no dialog after clicking yes :) but idk, maybe others find long presses intuitive
