It's no problem.
Now:
-There's a clipping problem with the side and back of the cliff chip you used in the Homicidal Side Quest; you can walk right through/over them.
-Similar clipping problem lets you walk up the walls in the Wax Cave. Also two of the monsters in Wax Cave4 use the same switch, so if you kill one they both disappear. That's the monster on the bridge and the one to the left of that one, switch 0434:radscorp3.
-Checking the body in Down the Hill, lower3 triggers a teleport event sending you back to the top of lower--- for some reason.
-Small thing in Hero Inner, the blood splatter graphic below the E is set to Same level as Hero, should be set to below.
-In the Fixed Bridge-Bridge Inner you can walk through the chip you used for the side walls.
-After the final Twitlight event cutscene the character sprites don't get removed.
-The teleport event to the mini garage in Domina is triggerd by the action key rather than when touched.
No more gamebreakers so far.
Edit: And I'm done the demo. That's all I've found.
