Really fun! It took a couple of plays before I understood what everything did, but it wasn't boring to figure out. Plus, once I figured it out, I played it several more times! I also really loved your level design. Very fun corridors and nice flow. I would love to have this as a LAN party game.
I think you ran into a similar issue that I had with my enemies where the collision capsule remained after you simulated physics on the static mesh. I found that you can disable the collision on the capsule when the character dies. That way it is only in the level and not colliding with the player.
