Ratings and reviews

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

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.

Love the game mechanics, but progress is excessively slow at starburst, especially with how grindy each reset is. could use stronger upgrades (higher boosts to element gain) and more "keep previous upgrades" options. Edit: Persevered throw starburst and it gets more fun
