DungeonQuest is a multiplayer platformer-RPG. 2-4 players cooperate in local multiplayer to explore dungeons and defeat enemies, gathering loot and leveling up.
Here's one of the first level design sketches of DungeonQuest.
The first room shows a door, a table and two chairs, a big lamp, a bookshelf, and a secret passage to a corridor. The corridor shows a floor hole trap with spikes, a dart trap and stairs. The second room shows a switches and a tile mechanism to open spike gates. Also, there's a HeroQuest class: the falling rock.
