It’s good overall. It definitely needs some improvements, but most of them are minor tweaks. It’s a solid base and fun to play.

A few things:

-I agree with Stig’s comment: the hovering feels a bit annoying. I can’t quite pinpoint why, but it comes off as too intrusive. -It needs an “auto-convert” button or upgrade for the endgame (before prestige). -There are no legends on the resources panel, and it’s sometimes unclear what’s what. For example, there are essences, then “(icon) essence” and in the stats panel there are summonings and siphons, but I don’t understand what “/action” means. It all feels a bit convoluted, it really needs a help page. Right now, I’m mostly clicking, upgrading, and buying without enough information to make strategic decisions. -Whenever I buy a Summoner or a Siphoner, the stats panel doesn’t change. It would be nice to see the numbers update immediately, some clear feedback that shows the impact of the purchase. Otherwise, the gameplay feels less meaningful. -The art is awesome, kind of like "What Lurks Below" or "Tower Wizard". That said, it makes the buttons a bit too small and slightly annoying to click. I’d love for them to be a bit bigger or for the upgrades to have a bit of line spacing. -A small detail: the void doesn’t grow. It would be cool if it expanded gradually over time. -I’m also not a fan of hidden prestige upgrades. They make it hard to decide when to prestige, since I don’t know if I’ll have enough shards to buy what I want. I’d prefer to see the upgrade tree beforehand so I can plan ahead and know exactly how many prestige shards I need for the upgrades I’m aiming for.

As I said, overrall is a good base that needs a few tweaks, but you're on the right track, it's fun and satisfying to play.

Hope it helps.
