It is exactly the game it advertises itself to be (a depressingly low bar), there are no ads, and it appears to be balanced for fun. Generous free resources, constant events to get easy stat boosts, and a steady sense of progression and improvement. One of the best casual mobile games I've played.

Still one of my favourite games ever, it's not my number 1, because I've played the game to completion multiple times since it's release and I'm happy that the creators are so active when it comes to updates... but the rocket ship needs to lead to a new planet in the next update please, maybe after beating the frozen and hell levels and getting to like level 25 or something, the rocket ship could become available, it could even just be like a restart button with an income multiplier

Great for just idling away some time. The game is actually possible to play for free. It takes a lot longer of course, but that's kind of what this game is. The game is a little unpolished in places, some of the terms are confusing in English, sometimes side objectives aren't real clear. But I enjoy the game, haven't experienced any bugs. I changed phones and had trouble getting the game on my new phone, I emailed support and they were great, understanding, and got it sorted out. Very helpful.
