v020 released!

Many big improvements have been made. It's still very much a work in progress, but it should be more enjoyable to play. I put a lot of effort into QoL and UX improvements this week, because I feel guilty pushing a bad UX onto you guys. I also added a bit of content, including 2 new level types, and the skeleton of the level selection system, where you select your next level via a transit station. Also, time progresses and your flashlight is toggleable for when it gets too dark. Cheers!
