The minute you step into the game, it welcomes you with a warm hug. I liked it. Hoa doesn't try to be something bigger than it is; it really is a simple little game. The art is stunning, the story is nice, the music is great, the gameplay makes use of mechanics that many other platformers do and it's fine! It's also a completely peaceful, meaning you can't die in any way, which is a huge part of its charm. You can just pick it up, play for a few hours without any major difficulty, and complete it with a nice feeling afterwards.
Can't even think of any cons, 'cause it's that simple. Definitely recommend it!
