I was a bit confused when the game loaded into a black room and I couldn't read the text because it was outside of the screen.
I eventually realized you have to maximize the game to see the instructions, and you need to scale up the lamp so everything isn't dark.
It might have been better to start with a level that is already lit up so new players don't think the game is bugged.
The scaling mechanic is cool. I have seen it a few times already though.
The UI is a bit basic, which is fine for a prototype, but it could use some love.
