Just started playing got to lvl 2/3. I'll admit, so far I'm impressed. I really do appreciate the old school feel to this game, they even went so far as to copy the 1st ed D&D module type face and art style, nostalgia is a wonderful thing. And it's a fun little game to boot. 5/5
Rogues are easily my favourite. Couple one with a decent mage tanked up with vampiric weapons and loads of regen they make awesome assassination teams for the annoying back rank enemies and bosses. (mages get lots of hp back when they use vampiric staff and lightning.
:-) you need to find a portal scroll (purple item drag onto portrait to use) there is one every even level and about 20% on odd ones. Later you can afford to buy Yelmo's seal (yellow star in orange box), use it once per level to visit shop.
I realise this game is governed by personal style, but here is a party that works well for me. front row= Cleric, Rogue 2nd row Ranger, Mage. I max out on as many items that regenerate hit points, my Rogue, Mage, and Ranger all are maxed out on vampiric weapons and the cleric has massive damage reflection. This way the characters' attack is simultaneous with their defence. Ranger's Nature's Balm is my most often used skill. Use rogue and either mage or ranger to assassinate anoying spell casters before they can cast spells. also when you have massive regenerate on all chars you can play a waiting game at the end of a fight to let your guys heal up before finishing the battle; means you are fresh for next fight (clerics call down holy light is invaluable for this tactic) :-)
