Im very proud to share this project "Stamp Tile Engine". This tile engine dosn't use the clone block but stamp the tile. That was so complicated to create code that make stamping tiles but its working and if you want you can use this to create your own game. I forget to put some note on the codes so I will make it for helping you. Ask me if you have any question !
