I love using it, its got a pretty steep learning curve but with a bit of help with the community, it made it 100x easier to learn how everything worked.

I use Linux (Ubuntu 24.04) and I encountered a lot of problems with the free version of JACK. It failed to find and open models for Half-Life, and couldn't find the existing directory for the compiler tools, so I was forced to seek out this paid version. I've not used JACK extensively at the time of this review, but it was easy to get started and I was able to quickly compile and test a room. All other recent reviews for Steam's version of JACK are positive, so this lead me to the purchase and I've can vouch for a great starter experience.
dark mode makes it infinitely better than the free version
Hammer pero bien hecho
