As others have said, the concept is great. I think you did a fantastic job with the gameplay feel and graphics, it looks very polished. I find it impressive that you managed to create a tileset with floor tiles at such a low resolution and still have recognizable objects and entities, it's just not something you see every day. The gameplay did lack depth though, enemies don't move and there's barely any real challenge. It does feel pointless after some time. Walking mindlessly through the darkness, earning money, killing creatures that don't react, as some sort of dark joke from the developer. Pretty nihilistic if you ask me. It's probably not what you intend, but I like it! Reminds me of one of my projects, maybe we should work together :P
