Thank you for your words ^^
For me, the tricks for organize the time in this jam are:
1. GDD. Create a Game Design Document-style draft on paper, even if it’s just a rough outline, that describes the lore, the texts (if you like to include narrative in the video game, like me, hehe), the nuclear mechanics in as much detail as possible, and the level design.
2. Gather a list of components. Write down the sprites and assets you’ll need, as well as audio effects and music. I already had some sprites downloaded from other projects, so it was easy to select them and have them ready to implement when I started programming.
3. Choose what to sacrifice. In the middle of the process, choose what you won’t have time for, but don’t give up on what counts the most. At this point, you can stop the clock and rethink in the document what can be eliminated. In my project, I had other additional mechanics, enemies, more music, many more sound effects, a menu… As always, it was overly ambitious. In the end, it remains a prototype for learning the mechanics and a platform puzzle, but nothing more.
4. Motor vantages (I think). GDevelop 5 is cool for desing prototypes quick. It automates some basic processes in its visual style programming, which saves you a lot of time :P I don’t know how to program with a programming language, but I am starting to have proficiency in using this video game engine.
