i feel like the progress in game is a bit slow, it takes a lot of time to upgrade your gear and when you do it's almost the same. I also didnt like too much the fact that i needed to farm 100 jewls to unlock red planet, when you reach the core and talk to that broken miner it should reward the new planet
 "Upgrade Complete 3"){kind=icon}
 "Reach the core"){kind=icon}
 "Not A Red Button"){kind=icon}
