The combat and setpieces really are the highlight here, showing just how far the reinterpretation could go. The fact the maps could be either very different or more like remakes keeps you on your toes. I found a few issues, however (obvious spoilers):

• Transparent Liquids do not work, seemingly because of it being a separate scenario. It's unfortunate, they'd look really good with the architecture.

• In "Things Betwixt Gender Coffin", there is a potential softlock. A slow-raising door that leads to one of the breakables can actually be closed by one of the aliens hiding behind it. I realized what had happened a bit too late...

• The door near the second terminal in "Major Exercise Agnostic Thermogenesis" that you open from behind has a strange noclip-like effect if you walk into it while it's closed.

• There's some sort of texture oversight in "Do Flares Come Standard?" that sticks out particularly, where one of the elevators is made fully out of ill-fitting door textures.

• In the very final battle of the set, many enemies will end up just standing around doing nothing because of the vanilla AI limits (presumably), although you might consider this a non-issue.

There was also a red barrel sprite that... danced(?) by mirroring itself, but somehow I felt that was intentional...
