Before I begin my review, I would like to state something very important.

This game has strong ties to the study of Computer Science. When I first started playing it, it reminded me of coding. Upon further research, I found out that this game is, in fact, Turing complete[en.wikipedia.org], which means that it can be used to simulate a computer. Below are two links demonstrating the fact.

Here is a Youtube Video demonstrating Turing completeness in Baba Is You

Here is a Reddit Post discussing Turing completeness in Baba Is You

Below are some videos showing you that Baba Is You can simulate games:

2048

The Witness

Conway's Game of Life

Sudoku

Snake

Pac-Man

Bomberman

Tetris

Pong

It can also play music!

Megalovania - Toby Fox

Never gonna give you up - Rick Astley

Anyways, here's my review:

Puzzles in this game are mind-boggling, unique, and fun. Never for a moment did I get bored in this game. The design is simple, the mechanics are well introduced, and the characters (i.e., objects/classes) are extremely cute. I'm a huge fan of BABA and KEKE, but I'm a little bit startled as to why you get BAKE BAKE when you put the two names together.

As for difficulty, for those of you who enjoy coding, I strongly believe that this game will be as difficult as debugging your work (you know how much the difficulty varies). For those of you who don't have any prior experience with coding, I feel as though you'll find the game more difficult than coders will find, but you should still be able to solve the puzzles (props to the developer for this!) while also gaining insight into the field of Computer Science. Heck, it might even inspire you to be a programmer!

TLDR: This game pleases both programmers and non-programmers, but in different ways.
