Here’s the official walkthrough for Mystique Chapter 1: Foetus posted on the developers website so if you are having trouble with the first part, here you go.
1. Grab the flashlight. If you stand on the pentagram and look at the bottom left side of the tub, you will see something on the floor. Tap it for a closer look, then grab the flashlight.
2. Grab the hammer. On the bottom right side of the tub is the hammer. Again, you need to be looking down to see it before you can zoom in.
3. Grab the shaver and the plaster. Open up the cabinet on the wall to find both items sitting inside.
4. Grab the toothbrush. Look in the back of the toilet and you will see the dirty toothbrush.
5. Get the key. Return to the tub and tap the handle to drain it. After that, select the toothbrush and then tap the shiny object to get the key.
6. Charge the shaver. Place the shaver in the charger by the mirror and then remove it after the cut scene is over.
7. Grab the circular saw. It is located on the right side under the sink.
8. Get the screwdriver and pliers. Look on the left side under the sink to find a locked tool box. Select the key and use it on the box. When it opens you will find the two items.
9. Get the batteries. Select the shaver and use the screw driver on it.
10. Turn on the flashlight. Select the flashlight and use the batteries on it. Tap the light again to turn it on.
11. Crush the wall with the hammer. Stand in front of the wall where it is sparking and use the hammer on the wall.
12. Get the electrical wiring. Use the pliers where you smashed the wall to remove the wire.
13. Fix the circular saw. First select the saw and then combine the wire with it. Once the wire is attached, use the plaster to repair the wire.
14. Escape from the room. Plug the saw into the outlet by the toilet then use the saw on the door to escape.
