Here is my walkthrough for level 4 of can you escape horror.
Get the blue cloth on the door and use it to wipe the mirrors to get the clue (crown, leaves and hand). Tap the cupboard until the symbol appears as in the mirrors.
Once the cupboard is open look for the colors, purple, blue and orange.Now got to the panel to the right of the door and tap until the mentioned colors appear, the panel will open revealing the remote. Here is one shortcut, once the remote is used, you will get the numbers 4781(red, brown, purple and yellow). Use the same numbers on the door to move to next level.
