4인 협동으로만 고난이도 가능한게 목표였노



Difficulty is indeed fine. You can absolutely kill bugs and blow shit up with the stuff we have on offer. Try the changes out and see what you think.
If it's just stomping you want I suggest dropping down a difficulty or two if it the higher difficulties are too hard.
Our vision is that you can only clear the highest difficulty with a perfectly coordinated team that all have a specialization that synergizes with the others in the group. We might not be quite there yet, but that's what we're aiming for.
