Before i try - any differences between this and good old robo miner?
oh i see limited upgrades, limited levels here on screenshots...
Robo Miner has an otion to remove ads with IAP - give it a try, it's pretty small to download maybe you like it.
Try Robo Miner - it may fit
I made other games as well for the "waiting times" of the day. Worm Puncher is another one.
What game are you refering to?
Only one I could find is "Robo Miner"
