DLC Quest is an amusing game that rightly pokes fun at the gaming industry while at the same time being a genuinely fun platformer.
The game is divided into two parts. First part is easy and won't really challenge too much, except maybe finding all the hidden items. The second part has a moderate challenge that adds wall-jumping (which Player must earn by getting the DLC), spikes and a hilarious ending. It's great to play a game that makes you laugh most of the way through. Also, for 100% achievement hunters, this game's list of achievements is short and reasonable.
Perhaps not worth full price since the playing time is about 3 hours, but recommended whenever on sale.
EDIT: changed "The game is broken" to "The game is divided" ...
