tl;dr -> In our hero's desperate search for his lost sister, he will invade various biomes, brutally maiming any animal he comes across. 11/10 realistic simulator showing how man destroys everything he encounters - even random animals protecting their territories. Maybe the sister ran away because her brother is a psychopath.
If you enjoy atmospheric platformers, challenging - yet intuitive - puzzles, and a grim/dark style, then you will really enjoy this game.
The aesthetics are great - although they are simple, the dark artstyle is very good at creating a desolate atmosphere during your journey through Limbo. For a 2D, black-and-white platformer, the death animations are plentiful and fairly gory - I was very impressed with the variety of deaths you can encounter. The sounds and ambient music are also good and help add to the vibe of the game. The way the chapters flow together is well-done, so nothing seems too ridiculous or crazy.
The controls are simple to learn. There isn't really a tutorial, as you learn everything slowly (the pacing in the game's difficulty is very well done, like Super Meat Boy). The learning curve is minimal to moderate depending on your experience with puzzle platformers. A lot of the solutions are intuitive, and will eventually reveal themselves to you in a moment of insight if you just keep persisting and applying trial and error. The checkpoint system is very fair and well-plotted out - you will not have to repeat entire puzzle segments often.
The variety of puzzle types is fantastic, always added in at a reasonable pace. Many include item manipulation like moving boxes, carts, etc. Eventually, you will also have to plan around momentum - for example, you may have to push a cart down a two-way slope so you can climb jump off of it onto a higher platform. There is a fair amount of timing-based puzzles, but the windows for error are always good. An interesting element is this leech-type animal that sometimes implants itself on your head. When this happens, it will keep moving your character in one direction - you can still jump, slow down your pace, and push objects. Any beams of light will cause the organism to turn you around, and the only way to remove the pest is to reach a hanging animal that will eat it.
For achievement hunters, the extra collectibles are fun to look for, and trying for a no-death playthrough can be intense and satisfying if you manage to complete it.
Overall, the game is a lot of fun for anyone into the puzzle platforming genre, and the execution and presentation delivers a very nice final product.
