I'm pretty much 1:1 in opinion with Stealthness - I really like the presentation of your game, but the requirements to move up each time to the next tier of drill was too slow to remain engaging. Try playing around with the numbers a bit more and see how it plays!

Great game! The idea is good but I think it would be more interesting if you added some twist to the minerals after the first one, so that the game changes a bit while you are playing. If you haven't yet, you can check other games from the incremental genre for inspiration. I'm very impressed that you made this game at 14 years old, I hope that you will keep making games!

I got the basic idea of the game, but the balance was wrong, and there were too many clicks to get the next upgrade (unless I had missed something). This is a shame because I think it could be engaging with the right gameplay balance. Otherwise, the style and presentation were good. A game with potential with more time
