I really like the art style and the controls. It took me a while to figure out what your instructions on how to use inventory items worked, but once I figured it out and solved the fuse box puzzle, i really like how it works. A note for the main release, which I hope there is... make a hotspot on the inventory item cursor. I naturally wanted to point the top left corner of the fuse at the fusebox, but it wouldn't register until it was uncomfortably off to the side.
Really nice start, I very much hope you continue it!
