The only odd thing is that all mercenaries you employ in the guild look like more or less ugly monsters (out of the Scoundrel that looks human). I was expecting a more classic D&D roster from what i had read of Gloomhaven.
The tutorial is nice, after a couple of actual tutorial missions, the other tutorial missions are in fact mini-puzzles you need to solve with each characters, finding how and when to use their various cards, and which cards to choose for a given situation (there's only 1 solution at each puzzle).
That Cragheart guy with his retaliation abilities seems to be a room killing monster, though it can be costly in health.
edit : started a campaign , took a brute and a scoundrel.
went to the only available scenario at that point "black barrow".
So it consist of 3 rooms and some enemies to kill in each, with the scenario requiring every of them being killed.
1st attempt : cleared the 2 first rooms and both my mercs became exhausted in the last room, burning card is something you really should avoid doing (and resting burn cards)
2nd attempt : managed better once i understood that you should NOT take your time (as waiting some turn will mean you'll use a rest option more often, forcing you to burn cards to refill your hand, cards that would have been usefull to avoid exhaustation) and just before entering the last room with my brute i noticed the "open door" action oddly didn't appeared ?
But i still played my move action to land in front of the door.
The brute decided to walk there as expected, but much less expected he decided to then spin on himself for a dozen of seconds, and then he decided to just walk all the way to the wall next the exit (despite not having enough move point to that), then walk through that wall into the void outside of the map.
At some point the brute stopped , but the game was still playing (i was surprised it didn't crashed), i had to again exhaust both him and the scoundrel cards again to end the mission in failure (but at least getting the money looted to buy some equipment in town) because that idiot was unable to come back to the map anymore.
