Yesterday I reached level 23 where a dragon toasted me. Didn't get "you die" message. The game just restarted. It was just after I drank healing potion. Possibly my new hit points were not enough to survive a hit from the beast. Argh.
Other problems:
1) With backflip power you can enter walls.

Move northwest. Under this logic backflip should place you into a wall ... so it does not happen and you go forward instead of checking for wall jump which would be appropriate here. Also, I wait with taking backflip as long as possible because it ruins wall jump in many cases.
2) Nymphs may steal equipped items. Then these disappear from your inventory but are still wielded / worn. You get more space without having to drop things.
Yes, this game is definitely fun. I would go as far as saying it is the first time you managed to capture the joy of playing original Rogue in 7DRL.
I think lost strength from ants is not recoverable on purpose. Lost max hp from wraiths cannot be restored even by drinking healing potions at full health.
Edit: My browser is Opera and, like Jo, I had to hit space first to be dropped in the dungeon.
