Thanks for submitting the game to the jam - it doesn't matter that you needed to get a bunch of stuff done after the deadline - its all about creativity and sharing in a positive environment - so we're glad you submitted.

I think the concept could be interesting - the main unique selling point to me is the block above the one you knock out falling down. So if you could play into that mechanic a little more, it may give you a more unique playing experience. However, you could also just keep it simple and make a style of game which doesn't need a unique concept, but instead just be "your flavour" of a digging / hoarding game. Really cute sprite work and animation as always java, enjoy the future development of this project!

I dug down into cocoa puffs!

All was good.

I kept digging, the ceiling above me betrayed me into a river of chocolate milk.

I continued.

The world grew slower, the computer got hot, fans kicked on.

It crashed.

Perfect example of what would happen if I became a miner, thanks for the game!
