It’s quite a testament for a Ludum Dare game to hold my attention for multiple and repeated playthroughs, and even affording it the “right” to live in my Steam library as a shortcut and that’s why I am mentioning it here.
One part roguelike, one part Spelunky, add a time restriction and you got Flooded Dungeons, an unbelievably well polished and addicting game made in 48 hours.
