How does the game fit the theme?
In Slug Quest, you play as a slug, who has to find a cookie in a desert. The game is also hard.

What code and assets did you not make from scratch during the jam (if any)?
This game uses the following GDevelop extensions that I did not make from scratch during the jam:
"Object "Is On Screen?" Detection" extension by Bouh, Silver-Streak, and VictrisGames

The sprites of the slug are recycled and modified from the sprites of the slug as seen in Slug Feeding. The recycled sprites of the slug are also recycled and modified for the green slimes.
The sprites of the bananas are recycled and modified from the sprites of the bananas as seen in Slug Feeding.
The sprites of the asteroids are recycled and modified from the sprites of the asteroids as seen in Schleifenstrecke.
The sounds from this game are recycled from the sounds as heard in "Eric & Yannik 2" (and "Eric & Yannik X", if you count one sound that has been recycled but got unused in Slug Quest).
And those are the assets that I did make but weren't made from scratch during the jam but were recycled and modified for the game during the jam.

As for the assets that I didn't make from scratch during the jam, I used -Race around the world- by Waterflame (licensed under CC BY-NC-SA 3.0) as the music for this game.
