man, it's so close to a 5 star for the type of game it is. After you start getting into billions the game starts to become very idle and not much to do, the upgrades become a full days wait basically. I like the game, I'm addicted, don't get me wrong, but I want to be able to prestige before collecting all the upgrades, it would make the game more enjoyable.

Nice concept and interesting pixelized 8-bit graphic. But current game version has a weird bug. Purchasing scientific upgrade that should automatically sell energy in fact does nothing. You still have to boringly press power-to-cash button and convert it manually. Game progresses quickly to the level where energy production is high (that's the whole idea why auto-sell upgrade is one of the first) the whole game experience turns into pressing power-to-cash button every second and nothing more.

This game is so great, in-game purchases are cheap so I recommend buying them to help support the devs... ads are optional and the gameplay is simple yet strategical, it's really fun and ennoyable. It does need an update with more space, more types of power sources between the first and last, and more research options, there is 1 bug where the very top of the screen is difficult to access without zooming in. But overall the game is great and deserves more attention.
