Man I loved playing motherload as a kid and this brought me back! Awesome Gameboy feel! The mining machine and little mole sprites are adorable and I liked how seamlessly the music changed so seamlessly between zones.
The moles stealing my gold was kind of a bummer and I found it hard to ever afford upgrades due to the rent increases. It was also a little awkward when you only mined 1 rock. You kinda have to sit on a seam to double mine or you would kinda get stuck in a lil hole.
Overall though, this was really fun and really hit me in the nostalgia!
