Hey, this is a good start for a first jam. Alas, having to restart the whole game if you fluff it up is annoying and drains out the fun pretty quickly, for me (I know someone who would perseveer!). I like the torchlit 8-bit style lighting, except the exit should be more clearly identifiable. Maybe the bottles should be big and small, or have up/down arrows on them? I kept forgetting which was which. When big miner moves blocks, it should be a consistent distance, seemed to change between 2nd/3rd level, I'd rather they didn't shove it away, but I sense that's part of the puzzle-solving.
