Drill Down

its a good automation game if you dont like story or enemys and instead want to work your way through things at your own pace

Just boosting the rating on this game because it's super underrated. :) Quite a simple automation game but that's totally acceptable for the price. Used to be known as Quarry. If I want to play an automation game and not in the mood for something as advanced or active as Factorio, Satisfactory, Mindustry or Dyson Sphere Program, this is the game I go to. I very rarely play mobile games but also have this on mobile, it's a fraction of the price and a fine port with no feature removal as far as I can tell.

The game concept is a wonderful idea but horribly flawed in key areas. The UI reminds me of 1980s menu design. I should know: I coded text menus on IBM midranges during that time period. If you don't know how to build a material required for a structure, you have to go to the previous menu, manually hunt for a structure that makes that material....only to discover it too requires materials you do not know how to make, so you have to go up the menu path again to manually search for more structures that make that material. Once a structure is set down, you cannot move it so you have to blow it up ....and do not get the materials back. The world is set in a very small finite space. If you run out of space, you run out of ways to build and that's game over.
