In general, behavior documentation can be accessed by clicking the "Help" button in their settings panel. You can add a custom behavior by selecting it from the "Logic & Math" section in the behavior editor (added at the bottom).
The behavior docs are sparse for this one, since it doesn't have any logic by default. Once you add the behavior and open its code editor, there is a "How Does This Work" button at the top, which has a short getting started guide. The code editor itself also has several templates to start from.
I'll be adding a Custom Behaviors section to the behaviors documentation on the site as well, but that's not live yet.
The prize will go to the person who submits the game. If you're working in a team, you should figure out up front who should get the Steam Deck, and have that person submit the game with their Itch.io account.
Really nice work! A serious upgrade from the original game jam version, I'm glad you decided to publish a definitive edition that's closer to your original vision.
You can use music from other games as long as you have permission from the copyright holder to use their music, yes. If you don't know whether you have permission to use a particular song, then then answer is probably no.
There is a lot of licensed music included in Flowlab, and a lot of Creative Commons licensed music here on Itch as well, if you are looking for music to use.
Hey Gustavo, I think this space shooter asset pack would be a great addition to my project - the Flowlab game maker (https://flowlab.io). Would that be OK with you?
