Haha, I think you haven't played recently, .
I'm caught red handed. Yeah, I was travelling these past few days - it's great to get yourself outside for a night or two.
Shiren The Wanderer has a monster that turns your items into riceballs, and it's one of my favorite roguelike monsters.
I haven't played Shiren, but that does sound good. Monsters whose attack can sometimes actually be beneficial to the player are cool. In Ragnarok/Valhalla, for example, there is a mage whose spells polymorph your inventory - a true disaster if you get your equipment and priced scrolls tunred into junk, but you can also drop everything but junk and do some third-party assisted polypiling for better items. I personally like such trade-offs.
However, in Hero Trap specifically I think an unlucky roll on an item destruction could make the game unwinnable really easily.
Yeah, that's definitely true.
Finally beat my own game.
