Update 0.0.2

Hello! And welcome to update 0.0.2!

This added some new blocks like grass and dirt!

also I've added a sky texture so it doesn't look bland to look at while playing!

I've also made some optimizations when reading the file

that's pretty much it for this

Also, I forgot to mention this in the readme but pressing the R key reloads the file so you don't have to open and close the game
