Ling Hun is a puzzle platformer; it's twist is that you can't exactly control your jump - your jumps always be in a 45 degree up in the direction you are facing, but you can change your direction once to down in a 45 degree when you "jump" again in midair.
So with that mechanic you have to find out where and when to "jump" to get through a level. Also the game adds a new mechanic to the existing gameplay like switches or extra "jumps" in each of its zone (a set of multiple levels).
You have to complete a zone from start to finish to complete it; if you quit while in a zone, you'll have to start the zone from the beginning next time.
The game also features two options for game pace: one is slower paced, so you have more time to react what is happening and one is faster paced, which is great if you are used to such games or want to speedrun it.
Are you already wondering about the story of the game? Well it's really simple: a fox stole your soul and you want to take it back.
Also the sound/music of the game is not something real special, but also not bad - so even if you have to try for an eternity on a level, it won't get annoying ... well if you don't have a problem with the fox laughing at you for every death you take.

I really liked the game and I even did all zones with zero deaths, which I'm normally not a big fan of, but I really had fun figuring out the levels and it wasn't extremly hard or unfair so I even went for those achievements. Well, except for one level, which annoyed me a lot, because the jumps were to tight a one point; the dev answered my post in the forum to look into it and fix it though - so maybe it's already patched if you play it. :)

So if you are in for a little puzzle platformer, which lives through its gameplay, then I can really recommend this game even for it's full price.
