Dungeon Slog was released last year on mobile devices, but now has a web version available from Armor Games, and it's seriously addictive fun - so worth featuring again :)
"An exciting, vaguely roguelike action RPG!
- Blast your way through a randomly generated dungeon.
- You play as an archer, a wizard or a warrior, all with different strengths and weaknesses.
- Level up your stats, buy new items.
- Awesome magic abilities!"
