hard to give a number, i work on it sporadically, and the last 2 years have been more about rewriting the engine and implementing future mechanics rather than adding content
the engine rewrite is nearly done though, got the physics almost identical to crash 3, much smoother camera, bunch of quality of life changes and polish. still gotta rip a bunch of level graphics from the gba games, but other than that i'm not too far away from being able to just work on levels
closer to 7.5 warp rooms, probably
