Great game.
Just a few things to note.
As everyone said, the BGM needs a slider. Aside from it being repetitive and annoying, it's too loud for what is a stealth game. I had no clue if the radio was turned off because of it.
2. The chairs near the wall in the day scene make the character go up which gets him caught. This along with the unskippable intro scene make this game very frusterating.
Otherwise this game is great and has a lot of potential. Expecially if more exploitation is added with particular characters.
