These are my thoughts:
- main problem is that some monsters (skaarj, slith, flys) have to be killed on the ground floor (they don't die if falling from the isles)
- you can fly under the isles with the nukes/redeemers, don't know if that is intended
- in the start room one light lamp has a graphical issue (using opengl here), see picture. a white square is shown there
- the red button in the house with the tentacles shows no text if pressed, but the other red button in the other house does
- one teleporter shows error message "Teleport destination for [...].VisibleTeleporter1 not found" and does not work
- for the mantas I would set more spawn points, as far as I can see there is only one point and spawning is slow
