Impossible to play until you discover that half of the interactables require a double-tap of 'E'. I'm not sure why, but tapping once and reading the message then tapping again just dismisses the message.

so e.g. you can't even see the safe unless you double-tap the closet.

After you know that it works fine.

Oh, wow! Excellent game! I love the ambient and the sound! Good job, team!
