Testing Collision
View Game is how you can test your collision as you drag the player around across the map with your mouse pointer. It's almost as if you were playing the game...
You can also use this mode to test out any foreground tiles you missed! It saves a ton of time compared to testing your map changes after saving, compiling, and playing through an emulator.
There isn't much else to this mode, but you can customize the display in the editor!
