Tundra Trek was just a suggestion I made. Nobody disagreed. I guess it can be renamed again later if it doesn't fit the level.
Edit: An early view of the lab set in action. I won't post the tileset yet, as all you could make are empty rooms. I was thinking I'd make the interiors so you exit with a shift-on-touch at a side. It would work really well with the igloo too. I might be adding too much detail. In the future there will be electronics with blue lights, specimen tanks, and office furniture. The tube light (Bank8, Objects 3-5) would work well, but I may make some special glow effect for them if there's room.
