I like your game. The title "Moon Miner" is very catchy. However, the game is too easy to be a real puzzle. Maybe bigger levels and items that could buy you more steps could make this game really hard (and fun).
Thanks. The type of game I make usually is just platformers or other arcade-y like things. I'm not very good at making puzzles. But this is my second attempt at this kind of game, so maybe I'll make a harder one next time.
