The soundtrack and visuals are great, but it can make you feel like a real idiot when you can't figure out such a simple game. I solved it in a lot more time than it should take but I did in the end, be it quite frustrated. Definitely played better with others so they can tell you when you're overlooking something.
my new game Myrtilles is available now ^^ https://nonomiyo.itch.io/myrtilles-escape-game it is a bit longer (about 1 hour playthrough) but I'm not sure it is easier :P
