Is it allowed to use own built Level Editors in the LD?

Hi, first timer here, I am wondering if I am allowed to use a Level Editor that I have built myself, for the next upcoming LD? Or is that still considered ‘Part of the process’ that you create a level editor during the 48 hours?

The level editor was built from scratch by myself, and creates 2 files for the map (One for tiles, and one for collisions), which can be used in a game (Of course with the proper “loading the map” code).

I am wondering whether i should work on this some more, or just start from scratch again during the LD.

Also if it is required, I will also provide the source code to it with the game from the LD.

Thanks!
