I’m pretty sure you’re not the only one who said that. But it unfortunately had to be scrapped, because not every players would use any feature like scripting and stuff due to how complicated it is and not to mention that Johnster had IRL stuff to do and he even finds it too complicated.
Floor Maker will fix that and make levels so much easier and fun to create. It also has better performance compared to the scrapped floor builder and it can go one million nodes, which is a huge improvement if you compare it to the scrapped floor builder prototype. I think you should wait a bit longer before saying the other is better, because they haven’t showcase more Floor Maker yet, so keep your expectations high.
