Place gunpowder, like redstone, which allows you to create a long fuse. It would be nice to have a small mod for this since the only other mod that exists with this feature has way more features than needed (Quark).
It seems easy enough, I got a few ideas on how I could make it different from existing mods, I'll get back to you :)
