That's fair enough about the turn skipping. Right now, I don't think the need to be near a wall makes any real difference, but perhaps if you decide to add new content, then it might do in the future. I would also say that the "push back" attacks of the zombie and giant-skeleton don't add anything much to the gameplay.
There's also a minor graphical glitch, as you can see here:
Note that most of the screen seems to be shifted left a bit, so some content on the left is cut off, and some stuff is visible at the right edge that probably shouldn't be. I get this every time I play. Possibly due to the way the screen in scaled?
I've just gone beyond level 200 without a game-over (only stopped due to boredom), but to be honest, I'm pretty certain it's possible to continue indefinitely. I did get reduced to skeleton form once or twice early on (due to starvation), and had to backtrack a bit to get money and a purple potion, but for the last hundred levels or so I've not been anywhere close to death.
Once I realised that ghosts don't attack you, and are actually very helpful (good for killing ghouls and giant-skeletons), that made the game a *lot* easier (same with fire). That's what I like most about this game - there's a real sense of discovery to the game mechanics.
Anyway, thanks again for the fun game! :)
