Nice game! Sadly a could not finish it because of bugs. Here are some things that I think could improve the game:
- Some UI that helps with the controls and goals (it was hard to find that "E" was the action key)
- The music choice was good, but it doesn't loop at all. It would be nice if it does, though
- The color choices for the walls and floor were a bit depressing. It's ok for the rat cave, but for the supermarket i think more vibrant colors would fit better with the atmosphere of that kind of places.
Altough all that, it has a lot of potential! Keep working on it!
