I can't tell if I'm bugging out or something else is happening - I never got a hint at the start of Level 21. Is it in words or throughout the level or what? I'm on Level 24 btw.
Suggestion: Make the arrows for the story Yellow - they totally blend into the background and I had no idea they were there till a user pointed them out to me!
For those that can't Idle when on another Tab, if on Google Chrome or FireFox - make the tab for the game be a completely different "browser" and it'll work.
I'm borderline ready to give up on Level 21... I got the hints, but after clicking the balls in the same direction 3 times in a row - it doesn't work. I mean, literally, the same ROW!
Suggestion: Add a means of creating a "Stopping Point" for the Stats gains. For example, if I set to Level 30, then it stops at Level 30 and refund my worker points.
Not for my sake, but I think it should have an "Are you sure?" pop-up when spending Rubies - just in case of an accidental misclick by someone when browsing the shop or the Skills page.
I don't know why, or whether it was on purpose, but for an Idle game I'm not allowed to view another tab and still make progress on this game. Really should change that or fix it.
We really need an 8x, 16x, and 32x speed for the Easy Waves. And don't tell me to skip them - because getting paid in Orange Blocks every 5 waves is the whole reason to not skip them.
Last comment before leaving, there needs to be a way to convert unnecessary cards (if desired) into Resources (Gold, Trees, Iron). Don't get me wrong, there's all sorts of strategies and uses for cards, but some cards just don't exactly meet our play style and I'd rather scrap them (such as, the Greedy Bird).
 "HP Atk Def"){kind=icon}
 "Multitask"){kind=icon}
 "GOSPACE"){kind=icon}
 "Unproportional"){kind=icon}
 "Idle Mine: Remix"){kind=icon}
 "green"){kind=icon}
 "Idle Quest"){kind=icon}
 "The Perfect Tower"){kind=icon}
 "The Chamber"){kind=icon}
 "Creature Card Idle"){kind=icon}
It shows you something important about how the arrows work.
