I am loving the game. It's a fully text-based incremental upgrades game with LOADS of upgrades and LOADS of prestiging required. On top of that, new worlds can be unlocked so you always have something to do somewhere, or a new upgrade which is just a few moments away. In-game premium currency is earned by playing and can be used for instant or permanent upgrades, depending on how patient you are.
Something I would like to see added is:
On the right of your income per second, I would like a number that shows the percentage upgrade of your current income per second that you would get if you buy certain things. This would activate when you hover the cursor over BUY, Next Milestone or Maximum Milestone, not every button, as you really don't need that information when buying a single item.
Another that might be nice is a 10-minute time warp that costs 1 or 2 diamonds, for those moments that 5 hours is way to much and you HAVE to go to bed!
