Very good game demo!! I like the interactivity than the game give to every object and also the story than have the game behind!! Good job :D
For me I only find tedious than for use an object you have to open your inventory, grab it and click on the object than you want to use it. For me I will make than you only click on the object and the character automatically use the object than have to use
For the rest the game is looking great!! Good luck working on it!!
