Ratings and reviews

unfortunately this game over complicates simple mechanics in favor of increased repetition and play time. its generally unstable and crashes every couple hours despite being touted as an 'active' idle game. great idea on paper but the initial 2 layers of prestige are entirely linear and underwhelming to say the least. the thirs layer of prestige is really where the meat and potatoes of the game lies. Again, this is stymied by elements that maintain manual interaction when they should be auto.

The skilled trees are always so incredibly unsatisfying and they do so little to help you move further in the game. I'm near the end of the large star explosions upgrades in the tree and the upgrades are such trash 1% reduction to cost and there's nothing else I can do to progress in this game further. so it's become very disappointing and I am uninstalling

*Developer response is a lie* Game features are heavily gated behind microtransactions (only free if you watch an ad). Not only is the base offline production timeframe a measly 5 minutes, but it's $3 to add 20 minutes to that! Blatant cash grab.
