I liked the aesthetic a lot! The solidly built, brightly coloured enemies work really well in VR, as do the sharp, low poly surroundings.
This is probably personal preference, but I didn't like that movement was head-relative. Since this is a dungeon crawler (and possibly also because I was playing seated) I had a clear idea in my mind of which direction my character was pointing within a cell, so it was always an awkward surprise when pushing forward moved me in a different direction. I know there are other people who absolutely demand head-relative movement, though, so I guess you can't please everybody!
Overall a pleasant little VR experience; hope you had fun making it!
