riddles and sieges is a medieval physics-based puzzler about one of the best things: destroying stuff. it's tile-based and concerns timing only in a sense that certain contraptions (the game calls them buildings for some reason) take more or less time to do their thing, so you have to set things up in an orderly fashion, like a chain reaction. let the quicker catapult destroy the tall tower before the slower trebuchet shoots over the ruins to demolish the castle behind it, stuff like that
