In which I play "Curse of the Lost Miner - Underground Madness Challenge" by BAKTRA Software from 2015. This is a puzzle game with action elements, in fact the puzzle aspect of it is almost entirely dependent on figuring out how to get your little happy face player character to move in the way that you want to collect all of the diamonds while not impaling yourself on spikes. Good puzzles, and reasonably fun to play. I think, though I'm not positive, that this is a compilation of the two games in this series, "Caverns of the Lost Miner" and "Curse of the Lost Miner".
