Ahahah the voice acting is so fun!
I really like how you managed the graphics all handpainted.
It really fits all well together.
The sound and the music are really cool.
It's a bit difficult to understand the keys and the doors. Maybe giving the keys a different color matching the door or just deleting the key once used could help a bit more understanding.
I liked the fact you ahve to manage your slots between equip and inventory.
Good job!
