If you have more than 1*10^12 gold, and you go to buy something on the trading post, all the resources are only at 9,999,999 but it will still take all your gold if you hit buy. This is weird because if you have less gold than that, you can buy more resources. And it's really inconvenient because if you're not paying attention you can lose a lot of gold. As the trading post is the main way to increase gold and resources late game, it makes it prohibitively hard to get the later upgrades/achievements.
I'm really liking this, it's a really solid idle/clicker game, but I feel like the layout of the different elements is really haphazard. It feels weird having the most important element (tree) off over in the lower right. I think it would look a little better if the tree was centered in the screen (with the health and money for it underneath centered). Then I'd move the statistics down where the tree currently is. I'd also suggest putting ca$h, DPS, and DPC all in one row, and moving the abilities down underneath the tree. And then put the hover text to the right of the save button. Also it just feels kind of inconsistent having borders around the percent upgrades but not the other upgrades you can buy. You know what... it'd be easier to explain in an image. Something like http://imgur.com/KSXHqcA except you could probably make it nicer looking. But maybe what feels natural to me would seem haphazard to you... I have no idea.
Thank you so much for your input, I really appreciate the effort you took to create the image. The feedback is really good and I will definitely looking into improving the UI based on your description. Again, thanks a lot.
