Oh yeah I forgot about that. So is this work going into Cube Royale or is it a side project?Check the date on that post
This is a fully separate thing. Due to some scheduling stuff I couldn't really be that productive with Cube Royale so instead I'm working on this atm.
It's a 4D game engine. In the future I might use it to make a game, but right now I'm just making sure the concept is viable. I don't know of anyone attempting to display a full 4D world before.
