0.20 Release

Big changes!

• Tutorial is broken again :P
• Completely revamped the base controls. Now everything is done through clicking and dragging the carts around.
• Carts and modules are now one and the same. Each module is one cart. You can re-order modules in the shop area.
• There are now distinct side weapons with bullets and top weapons that you can direct control.
• The engine is now a special piece. If you lose the engine you lose the game. You also get a special cargo. If you lose that you also lose the game.
• New Modules like ammo booster, damage booster, and barricade. Each help the carts next to them.
• Win screen is now an area. You need to drag your cargo to get your reward. Similarly you choose your next destination by picking between cargos instead of using the map. The map will play a bigger part later.
• New UI display for seeing the status of the entire train at once.
• New track switching warning sound and animation. Also the radar only shows "normal enemies" or "elite enemies" instead of all the enemies.
• When you switch tracks enemies leave.
