Clunky, yes, but kind of interesting! I can see things I'd improve (I made it to the second level before dying, which kind of undercut my original "it's kind of easy, isn't it?" comment), like possibly different-colored floors for adjacent rooms, specifically to help visually set apart multi-space rooms.
The "it seems easy" comment came from "oh just get the skeleton one space behind you and then it'll follow you but never reach you", which is great if it works, but it didn't particularly work by the time I got to the second level. I did get into a kind of stalemate, where I was in the fourth column and the skeleton was in the third, so I'd move up or down a row and it would move up or down a row to match me, so I was a move ahead of it but it blocked me every time. (Maybe I should look again with a little more attention to door-locking.)
But I think there's absolutely the core of an interesting game here.
