nice submission, I particularly liked the main character animations.

I am not sure if there is a goal, but if at some point you plan to do an iteration, you should consider either increasing the jump height or allowing to mine resources in diagonal (otherwise once you go down more than 1 block you cannot go back up.

Great visuals and sound effects, but I didn't figured out what is the won condition. "You won" just appeared, but I could still play the game and dig down until lava blocks.
