Nice looking game.
Although I have some suggestions, if you don't mind :
- First of all, it lacks some goal. Or at least I didn't understand what my goal is. I think you could show to me - the player - lead me to my goal;
- Talking about leading to the player's goal. I saw an orb in front of an open door. As the player I assume that if a door is open and has an orb in front of it, then I can go through the door and there will be more orbs. But I get stuck in the collider). Don't leave visually open doors which are closed technically. If the door was, for example, blocked by some furniture, then I as the player would think 'yeah, I can't go through here, I need to find another way';
- Make the grass transparent-ish when the player enters it.
