addictive game with great progression, i managed to get a stable loop by using mine-cart to get far fast. But then the game started lagging (probably because there was a lot of leftover coal, I stockpiled it as much as I could) And I died because I couldn't get back on surface with those lags. Maybe making coal be gone on the next day can make it more stable and create more tension. Also its very interesting that you created your own engine, how did you do it??

i didn't want to remove items at a new day because i though you would want to keep them on the ground for the next day, but i guess i couldn't foresee the amount of coal building up on the ground because of how much you get from mining
for the engine, I just handled all the game logic like objects and stuff myself instead of instead of using prebuilt stuff and rendered everything through code
