I love this game. It's FUN: my #1 reason for playing games.
The goal sounds simple: start in the tavern, work your way down to the 26th level, get the treasure, and bring it back up to the tavern, and you win. Simple, right? HA!
I usually play this game late in the evening, after I've done everything for the day and am winding down. I can't beat it, I can't even get close to beating it, but I enjoy every moment playing it. When I die, then I go to bed. ;-)
Legend of Dungeon is colorful and gorgeous. The pixel art style here is well drawn & attractive. The colored lighting of effects, with light sources & real-time shadows vault what might have been an "ordinary" pixel art game of the '90s into a beautiful, 21st century game.
It combines the randomly generated levels/rooms/monsters/objects of a rogue-like with a classic "beat 'em up" style of movement & gameplay which I enjoy more than normal 2-D side-scrollers or classic top-down games.
The neat quirks of this game keep it interesting. Everything's randomly generated, even the color of the potion bottles to their effects; different every game. The swing of your melee weapons need to be timed well to hit your enemy best: you don't just button mash. Spellbooks that shoot flaming skulls or spawn monster companions mix up your strategy as you go, as do rare projectile weapons. A spray paint can will help you mark your path on walls (or just vandalize the walls!). Sometimes you get a room with so many baddies, or really wicked ones, that the only thing you can do is RUN! Or get lucky and find a path of rooms around.
I really enjoy playing the Daily generated dungeon, and this is the only game where I've cared to know where my score ranks world-wide.
If I had to use 1 word to describe Legend of Dungeon: FUN.
2 words? Colorful fun. =)
