Thank you for making the game! I'm into the Normal Giant Raids, and so far I find the Ascension playstyle to be a bit boring. It feels the same as the post-rebirth Raids, but the raids take much longer and there not much else to do. This might not be as much of a problem if the game worked in the background, but at least on my system if I switch tabs then the game doesn't progress until I switch back, so I'm not able to do anything else on my computer while playing the game.
The scaling of the raid upgrades seems strange too, I shouldn't be able to max upgrade the final boss when I reach the normal raids.
Another bug I believe: When you upgrade the raids, the amount of GE you earn is updated on the main raid page, but it is not updated on the screen that pops up when you click Fight or on the popup after completing the fight. I think you're awarded the correct amount of GE, it's just not reflected in the text.
I know my post sounds negative, but I am enjoying playing the game and I look forward to seeing what else you do with it!
