The sheer volume of blockroaches to be dealt with is painful. Not a fan of 100% damage reduction. Maybe they could actually take that half damage they're shielding their allies from while outside their zone? Maybe split the damage if there are multiple blockers, or just damage one of them, may as well be random. And not take the damage while inside.
More than that though, bug with the interaction of those bugs and bear traps, possibly tripwires too, when they are pulled from a zone with 100% damage reduction to a bear trap, they don't take the traps damage, even though they should be outside the protected zone when the damage is dealt.
May want to clarify the wording on attacks and skills as to the timing of damage and movement, like that knight's attack does damage, then moves, and the boxing glove moves, then does damage. Or that they're simultaneous, though I don't know of any where that's the case and would be different from damage, then move. Seems like that sort of simultaneous event would be more likely to cause issues than not.
Lastly, reminder text for what status effects do on the skills that apply them would be very nice, I have more than enough to memorize as is, and I'd rather not have a notebook lying around for this sort of game.
