Is there any mod support?

Honestly, I have no idea. Do your own testing. Report mod compatibility bugs here.

Can I have multiple items in one package?

Sadly, no. This may become a feature in later updates though.

I found a package with no contents or label!! What do I do?

Report a bug on the GitHub repository and do not unpack it!

This mod is cool but I hate the sprites.

Not a question, but to answer the impending question, I will make the art better eventually.
Please don't make better sprites for me, I don't need them :)
