I'm in the 4th dungeon on UG4.
Ah, yes, that dungeon. That was pretty great. You absolutely HAVE to engage the Red SEO to get by. There is a way to do it, and once you figure it out, almost every Red SEO of that variety will become a non-threat if you're paying attention. I won't spoil it here, so start experimenting.
Could you talk about it a little, give a screenshot or two? I think I'd like to play it.
It's a pretty neat game. You could say it plays similarly to the Etrian Odyssey games. Run around dungeons. Beat stuff up. Get the ever-loving stuffing kicked out of you by SEOs (totally not FOEs). All that fun stuff. Character selection is limited though, as there are only the 4 characters you can get in your party.
If you're interested, there's a trial here:
