1. When calling a landlord and not searching the body for the key after killing him you can no longer find the key, at least now. Thank you for pointing this out! I'll find some way to fix that.
2. Unfortunately, the apartment scene is the only one that made it into the game jam submission, so when you try to leave the apartment, that's it. Asset-wise, we made 2 other levels that were ready to go, there just wasn't enough time to implement a story for those levels given our internal development issues. In retrospect, we'd have organized our work differently but it was a first game jam for most of our team. Sorry if it is disappointing (it certainly is for us that we managed to get in only so little content), but as I mentioned - we're working hard to release the originally-intended content right after jam.
