If we were ever to consider making an injectable client, we would probably just make it possible using the traditional LiquidBounce Nextgen, as it is already something of an injectable and it would be much easier to make it loadable at runtime. It would be limited to the specific version it was made for though, everything else would require tons of wrapper code.
LiquidBounce Lite, was a short trip from me towards writing a cheat directly in Rust - which wouldn't be a big deal, however, as you said, "EXE" or rather, should we make a cheat that requires Windows API is more problematic, as I'm on Linux and this cheat was therefore made on my Windows notebook, which is not something I was interested in doing further.
