We got to the deadline and couldn't place consumables properly :s, so there ARE heals in the game, just tucked away in a room you might easily miss.
The navigation part I must say was intended though. It was a small map so we made it very symmetrical so getting lost was part of the challenge. We wanted to add more decor to each room so they would be more recognizable between each other but in the end it couldn't be :c.
Glad you enjoyed it!
