I enjoyed the first run to global domination, which had a few hours of gameplay. I got up to Prestige 5 but burnt out. I would like to see a few features. Sorting - sort by cost of either Money or Happy. Deck stacking - reorder the card list in any way you want. Automation - automatically buy cards when available, based on the order the deck is stacked; each card can have a checkbox for whether automation is enabled. Interesting game, but in its current state it didn't feel worth the price.

notification acknowledgment simulator. it's resoundingly fine. there's no ads so I understand a price tag but this wasn't worth the price. there are some interesting cards and there is a lose condition which is interesting for an idle game. it comes down to stack happiness to unlock big dollar per hour returns. sort by affordable, navigate to bottom of list. buy anything that won't bankrupt you or set you on a negative income. there's 10 loops. took me under a week.

Very strange game. There is no offline progress... And there's also no active gameplay. You choose chards from a list of 400+, each card either increasing or decreasing various modifiers relating to your income per second. They aren't sorted in any way, so whenever you have enough to get a new card you have to search the full list to find which one is best to get. But it's free, with no iap, so you're not risking anything to try for yourself
