Concept and presentation wise, its a great game, especially for free. I love the educational angle of it too, but... it needs to make money still.

The game is made with an auto-clicker in mind because the numbers to upgrade as absurd. So even if I'm making 1 billion a second abusing an auto-clicker.
10 billion in 10 seconds
60 billion in 60 seconds (1 minute)
600 billion in 600 seconds (10 minutes)
1 Trillion in 1000 seconds (16.6 minutes)
Seems decent. When is the next upgrade. 5 Trillion! If my math is right that's almost 83 minutes, almost an hour and a half, for 1 upgrade.... of hundreds. This gain rate is just insane.

Honestly, I'd be more comfortable buying this at like $10 or $15 and having a consistent and realistic progression rate vs this wall of slog where you come back once a day and play for 5 minutes before you can't do anything else.

Edit: I just found out that income per click STOPS when you click on a 'Bonus' icon, which seem oddly programmed to fly at you if you spend to much time in one place clicking. Meaning you can't even leave this game auto-clicking over night. In fact, all income per second stops. Which means depending on when it hits you you can loose resource income. God that is just such a huge '♥♥♥♥ you' to the player.
