Thanks a lot mate! 😁
Hum, this isn't the first comment saying that the fact that deleting blocks take them back to your inventory was super clear at first so, if we ever work on that again I guess we'll need to address that issue with a better tutorial. 🤔
About your strategy tho, I do exactly the same xD. I delete blocks behind me because I want to give a big amount of blocks before hard times ahead.
