hey, i added the life meter.
i explained what i did and how it works in the event sheet.
i used a tiled background instead of a sprite,
it repeats vertically and horizontally, so you need to keep the height normal, and take the normal width, and multiply it by the number of lives.
at first i added a check to see if you had more than 0 lives, but at the end i dont think you need it, but i forgot to remove it.
what you need to do is make the plane respawn after dying.
i think it should work
if you have any questions let me know,
