I'm not working on this mod any more, but you can check out my other work over at lopcode.com and twitch.tv/carrot

EnderTech is intended to be a tech and Ender themed mod, starting at around Thermal Expansion's end-game. It will contain powerful, relatively expensive mechanics, with some configurability. The defaults will maintain a balance that makes my own game more fun.

Some features are often in development, so try to use Promoted builds in your world. It's still no guarantee that a recipe or cost won't change, but I'll try to make sure things carry over where possible.

Yes, you can use it in your (public) mod pack, as long as:

You aren't charging for access to items or the mod itself (Mojang's ToS applies),
You don't modify the Jar (it is appropriately signed and modifying it would break this).

Don't like the balance (eg: think it's too energy expensive)? Change it in the configuration!
