Leonard linked to You Only Live Once. I have not tried it, despite the “only about an hour of gameplay” label; I want to call attention to one element of the blurb.
Extremely tactical combat. There is no randomness in combat. You always hit and always do full damage. This means that careful placement is the difference between success and failure.
I can’t decide whether this is a terrible idea or complete freaking genius. (I assume it applies to the monsters as well.)
