I add the tiles to have the ground but when running, the window seems to show me a zoomed part.
For example, I positionned my player as yours and when running, it appears ritgh on the left side of the screen instead of a bit on the right: I don't see any ground or wall tilesets
my bad: I made a mistake and all I was running was the Player scene, not the LevelTemplate
everything went fine once I ran the proper scene :)
Good to know, glad you could find the solution!
