You probably haven't heard of Scratch Slash Mine.
It's a Minecraft/Terraria/General Sandbox clone that I built in 1.4. The 1.4 version is now known as Classic as cloning in 2.0 becomes my new focus for the full game, now known as Scratch Slash Mine 2.0.
It would be great to get some feedback and support on my project. Right now I could simply do with a few people to put in a team - Minecraft wouldn't be Minecraft if Notch didn't have Mojang. So if you'd like to be an artist, programmer, or simply an ideas guy, then please do contact me!
This project, I believe, has the potential to be something big - but I can only achieve that if I can get the great ideas and concepts that I need from other people.
