Very simple first generation idle game.
Upgrade mining equipment, level your scientists, and your workers to reach new areas, fight monsters, defeat boss monsters, and unlock subterranean cities.
The main cons of this game are no offline progression, a quest system that requires you to use two (or more) places to redeem quests, and a clunky combat system.
Overall, it's worth keeping if you like the genre.

Obviously, the base game has Academy award nominees, an amazing score, and high accolades.
However, the modding community has kept this masterpiece still riding high with constant additions, bug and dialogue fixes, and 100 times the content of the initial game. Affordable copies are out there on G2A and other sites: do yourself a favor and play it.

Don't let the simple graphics fool you: this is a wonderfully intricate idle game.
The amount of thought and planning that goes into each intertwined category is astounding.
Definitely a keeper if you can get past the initial learning curve.

Game used to crash a lot, but is now stable.
It's a rather pedestrian idle/clicker game with a mobile feel, no different from many others.
Gameplay comes down to swiping bills by clicking, then upgrading passive income, offline/AFK earnings potential, and your swiping power to level up. You earn additional items by leveling up and bonuses by completing leveled challenges. There are many cosmetic overrides that you can purchase, but they do little to keep interest in the game

There is no way to complete this game quickly; playing in daily bursts to check in and keep exponential growth happening is key. Use of an autoclicker and/or macro program is strongly recommended speed things along.
This is a tentative recommend since the crashing has been fixed. 6/10
