The biggest thing with remaking every map in the game and most of the elements from the ground up is that I lose a little vertical real estate and some horizontal size with the rooms, but SO FAR most room remakes have been 1:1 with way more detail.
Having the chance to just reevaluate everything I made in oldTASQ is pretty nice tbh.
Also those falling platforms are functionally the same as the ones in oldTASQ, but they actually respawn without requiring you to exit the region, lol
