You can get graphic tile sets for it! They're not quite as aesthetically fancy, and they don't streamline the controls like the official Steam version will, but there's still some very good ones. Edit the link for Quake taking priority:

Why the hell the project that has been in development since for over 5 years isn't a priority is baffling. The CM said on discord that Quake took priority. People seem to be giving them a whole lot of rope because of their love of SS and the kex ports but this project raises so many red flags.

they have given us nothing but concept and teaser for research that honestly looked really rough to me. They said at the beginning of the year that the game was finishing development and that they were opening up pre-orders to take our money. I would have a lot more respect for them if they told us how far along the game is and how long it will take. The fact that they don't have the transparency to come out and tell people that they game is delayed is beyond terrible. They were supposed in 2020 and that didn't happen.

Is anybody really surprised ? they were supposed to launch in 2017 and that never happened.
