I've played this for about 3-4 hours. Maybe a bit more, I'm unsure. I "unlocked" ascension. By that I mean the menu was opened, but it wouldn't be available for another... 10+ hours? Roughly? Its a guess. The level required + the gold required plus the slow animations means that each stage that you win is taking like 10 seconds, each stage gives like 1/8 of a level (again, roughly). So lets say a full minute per level with nothing rewarding in the mean time. Just waiting until you can upgrade a piece of gear x10 to get a synergy bonus, which is also INCREDIBLY lackluster.
Maybe I'm missing something. But this game feels like, even if you sped it up 5x or 10x, it'd still feel like a massive slog and unrewarding overall.
