A nice concept. Unfortunately, I wasn't able to collect the key. It seems a problem with collision as I couldn't collect the other items until I figured out I was too close. At least that's what it seems. The art was nice and fit the theme perfectly. I enjoyed the music too. A layout of the controls would have been good with an option to switch to wasd as I find the arrows a bit awkward especially when using e to interact.
Overall, a nice effort.
