TIC-80 is great indeed, I had even ore fu with it than with PICO-8 and that's a high bar.

But there is one gripe -- when packaging apps into executable, TIC-80 pulls templates from the Internet.

On one hand, it's not that big deal, we are online basically all time nowadays. But on the other hand, I would expect that kind of software to be self-contained.

I found a quite simple (but definitely not frictionless) workaround though - you can build the templates yourself, edit source code to work with localhost instead of TIC website, and host the templates on local webserver.

As I said, it's not a frictionless solution, but I don't know C well enough to make more substantial changes to this behaviour.
