Plan for Train Puzzle dot exe (title pending) 0.4:

UI/UX
-Settings menu and associated features as previously discussed
-add the 'dating sim' (display conductor and engineer characters and dialogue in front of each level). Mood calculation TBD.
-Replace level select with level tree.
-Movable camera (with limitations on how far the camera can move)
--Camera should snap to pixel grid and can NOT rotate.
--There needs to be limitations on where the camera can go, some kind of border or x/y position limitation.
--Mode where the camera follows the locomotive (but does not go beyond the border). Still must snap to pixel grid.
-when holding F key, render rolling stock and track on top of scenery objects?

Sound
-Rolling resistance sounds, with stuttering-sqealing in curves.
-3-chime synthesized whistle, ideally able to be quilled rather than just a static sound effect.

Game Mechanics
-Train cars run on two points rather than one.
-disable switch stand and play "clunk" noise when a car is fouling the switch.
-isn't there a mouse cursor that's like, got an x on it? use that when mousing over a fouled switch.
-Add turntables.

Levels
-Add randomized Timesaver with between 5 and 7 random cars in random spots and destinations.
-Turntable level based on that vintage puzzle toy I found.
-Roundhouse level.
-Longer/larger level variants to take advantage of moving camera.
-Triplenook?
-Timesaver variant where each car spot is replaced with a small spur with a few cars and the runaround is a little longer?

Train art
-Extra skins for the loco.
--Select in settings menu for now.
-convert more cars to PBR textures, especially weathered cars.
-chrome (stainless steel) reefer.

Scenery
-Implement roads, which can just be placeholder dark grey cuboids for now.
-Implement crossing gates which open when level is completed. (Model completed, needs to be put in-game)
-Modular roundhouse.
-Road/utility vehicle models for decoration (and to denote 'team tracks')
--Advanced steam tractor-trailer
--Diesel tractor-trailer
--electric van
--advanced steam tractor with variants.
--advanced steam mobile crane.
--Forklift.
-vertical tanks model.
-implement all tree models in-game.
-generic small warehouse.
-generic loading platform.
