An Idle game that is quite well done compared to others. Several aspects of the game make it worthwhile to play, and then keep playing.

1. It is one of the fewer Idle games with Leaderboards. You can try and actually compete with others!
2. The game continues even when you close it. This allows you to continue making money when you're busy doing something else.
3. The achievements benefit you nicely. Currently, each achievement reduces the time it takes for you to make money from each investment, depending on which achievements you get. There is also several achievements that increase the speed of all investments.
4. There are upgrades you can purchase that are extremely good and well worth it. The upgrades consist of increasing the benefit from Angel Investors (explained below) and increase each investment's profit by 3 times. The 3 times increase is available multiple times for each invesment, racking in loads more money!
5. There is an Angel Investors system, which is basically Prestige. It allows you to start over, but get a certain percetages more money next time. Each Angel Investor, without any upgrades, gives 2% more money. 10 Angel Investors = 20% more money from the investments you make.
6. The developer is active and responsive. He replies to many of the comments left on the game, letting people know what's going on and what plans are.
7. The game is actively being updated, which is unusual for an Idle game.

One of the few downsides, which is a problem for a lot of Idle games, is once you get so many investments (hundreds and hundreds of each), you can end up spending hours waiting to make enough money to buy as little as 1 more investment in any of the options. However, the developer has said he is working on stuff to be able to do to try and get rid of that, or maybe something else to occupy the time.

If you are a fan of Idle games, this would defintely be one that is worth your time. If you're not, you could give it a try anyway! This seems to be a well liked game, even by people who aren't usually fans of these types of games. Possibly due to the achievements.
