Been adding more tiles. Realized I need layers to avoid having to create every combination of floor + things on the floor. Putting off coding them until I have some idea what I'm really going to use this stuff for.
Joined #gamedev on freenode, started reading r/gamedev instead of my usual Hacker News sometimes. Noticed many people seem to make a tile engine but never progress anywhere after that. This alerted me to the need of adding some gameplay asap.
