This is a small update with some minor bug fixe, from after the completion of the jam. It still resembles what was in the jam, with the addition of a 3x3 big yellow house.  Small camera speed adjustments where made: slow down mouse right-click and drag, speed up rotation, speed up WASD.

Placing of objects (tracks/houses) has been fixed, it is now what you see is what it is. The follow crossing of tracks is no longer possible

Here is the new 3x3 big yellow house
