Miner Mania

Published as a type-in game in Your Sinclair magazine, Miner Mania is a platformer "inspired" by Jet Set Willy. Players control a miner searching for precious stones in a series of caverns on a distant planet. The player needs to move and jump through 10 caverns, collecting all the stones in each one to progress to the next, while avoiding falling boulders and bats that drain energy on contact.
