Sure, I'll second that. I sometimes play DoomRL like I play Doom- Hold down the move button, and twitch shoot. Which is bad. Having something that forces me to stop when my health is low should save a few poor bastard marines.
On a wholly unrelated note, I managed to kill the first boss. Dwarven Rangers wielding blessed copper flails with a blessed stunning willow bow ready to swap in for the win! :)
And I officially hate traps. Which gives me a thought. Glowie, have you considered giving players permanent, always active traits? For example, all classes get the same traits, but they get them in different orders. So while a Ranger might get Trap Sense (a trait that either gives you a bonus to dodging traps, or gives you a chance to see a trip before you trip it) at level 3 or so, a Fighter might not get the trait until level 9 or 10. The player doesn't choose the trait they receive, they get it automatically on level-up.
