It's not horrible and could be fun but the progress feels very off. The first few runs are fun since everything is new and the money gain prestiges are cheap and give a lot progress but after a few prestiges it gets more tiring than fun.

You have to actively watch the game to progress since you need to manually pick up the money but the manual progress is very stale since after level 18-ish it becomes a bit luck based if you win a level since there are no money upgrades to buy anymore leading to very slow progress but prestiging also feels weak since there are no cheap upgrades anymore so now i need to stare at the game idling for about an hour to get 1 prestige upgrade.

Besides that some upgrades just confuse me. The bronze ball looks golden? The normal and silver balls look the same? Not sure if there is a difference between the bronze and golden ball either and I have no clue what the "magic ball" upgrade does. I have triggered the mini ball about a hundred times while the magic ball upgrade didn't trigger (or i just don't see it i guess?). Also what does the ball effects peg bonus upgrade do? It doesn't do extra damage or give extra money so I'm confused.

A few suggestions: Add more money upgrades to progress faster past level 20. Add a way to automatically pass levels (a prestige upgrade that collects X% of the money at the end of the round maybe and progresses to the next level if won) and/or cheaper prestige upgrades.

Again it's not a horrible game. The base is good but I want to either let it idle on it's own or play it actively to get good progress but both are not possible right now so I can't recommend it. Also the fact that the game pauses when it's not rendered also makes any idle progress (even the passive money) impossible.
