Saving weapons in RPGs

I have an rpg game in the making for a few weeks, and there’s a collectible sword that you can grab and use to kill enemies(still in the making) and whenever I go to the next level, you don’t have the sword and everything you did in the previous level is undone, and I have no clue how to fix it, please help here is my game:

Use a save block. Make it to where when you get the sword, it sets that save to 1. Every time the game starts, have it test for that save. If it is one, then you are allowed to use the sword.
BTW, nice game.

Also, in “layers” add you columns and background blocks, not the game world. Or you could set the player’s display order to 2.
