Love the update!
So what are you going to focus on now? In your post you mentioned wanting to expand the Khrono tomb and I remember you mentioned adding another area on the way to the tomb. But do you plan on focusing on finishing the game overs for the current enemies for now and moving on to new parts later? You said that you like creating sprites the most you probabl don't want the backlog to become too much.
BTW, you'll probably wnat to make some adjustments to the memories room in the ankhrono replica. You're runing out of room to place sprites.
Maybe create a room for each area that looks like said area? Along with one room for miscellaneous scenes like the bondage toy testing scenes.
