The amount of bugs that I found was CRAZY.

I had to replay the game few times just to get to the bad ending and even then I turn around on the father and camera gets frozen(BUT NOT ON THE FATHER xD)

I had infinite battery, syringe with a green vile thing that gives you a tape player(lmao) in addition to another tape player that you picked up in the bedroom, AND THEY BOTH ARE COMPLETELY USEFUL because it's not like tapes can be played without them right? 

So yes removing useless things like playing piano makes a lot more sense now.

Checkpoints, oh let me start about the checkpoints xD  

If you so dare as to NOT follow the shadow but explore, checkpoint gets triggered and the door closed. Go upstairs, door closes; go to the kitchen, door closes; move anywhere but where shadow is leading you and door CLOSES. Also, remember that checkpoint that leads you back to the bedroom, yes, the one with curtains. If you won't go straight out of the door, you'll get stuck in the locked room mystery(how did I end up here).

Here are some extras for you:

You can play multiple tapes at the same time; 

you can stand in the way of the door and it wont close(I'm just assuming here that you don't want ppl to get stuck in the room with no exit);

battery is infinite and can be combined infinite amount of times, so finding new batteries is not a requirement.

Overall it was so dumb funny to play this game.

4/5 better add that piano back :)
