People who make these idle games should be required to play Candybox and A Dark Room first.
These games were successful because they had actual gameplay and story alongside the idling aspects.
Idle games like this one involve nothing more than clicking buttons and watching numbers go higher. Sometimes they have a 'click this button to watch your numbers get smaller' in the form of a 'battle' mechanic, like this one, but they're all essentially the exact same game with a different skin.
I think that there are enough idle games like this that you can't just get away with doing the same-old-same-old anymore.
Two stars because it seems polished, which is more than some can say, but it's still nothing special.
