It would be kinda cool to have a depth meter, where each block you destroy gets you deeper and deeper into the game world (be good for leaderboards too.....)
Also, a scroll button for the upgrades would be great, or alternatively, having the upgrades sorted by their price, so the cheapest is always first, would be helpful as well.
Beautiful game, and nothing to really complain about :)
Although, I must second some of Gastyz's suggestions, mainly making the "element/second" rates visible, and also making elements worth more, perhaps through making the mining rates for the other elements less than the rate for oxygen, for example.
But they're just small suggestions for minor things :)
Still a great idle game, and doubles as something relaxing to look at too!! :)
So realistically, it's only worth getting 1 of the comet, planet and star upgrades (just for the visual changes), and spending more CO2 on the "Special" upgrades
Blacksmith skill max: 130-131%
Blacksmith Expertise max: Level 10-11
Blacksmith Efficiency max: 50%
Autoclick Faster max: 13.51-14.22
Idle Power max: 100%
Upgrade Blacksmith: No max limit (will always be able to be increased)
Don't know about the others, as I haven't gotten up to their max values yet.
i reckon that once you upgrade everything you can to max, then you should consider the game finished, and post here with your final score (quality, power, etc.)
So glad you only have to click in the general direction of the next cell....having to click specifically on the next cell would make it SO much harder.....

Nope, I'm working at a basketball game right now. Anyway, I could think about doing a sequel
