Mega solid entry. Probably the strongest on this jam! The graphics is very nice and consistent. The cutscenes are awesome. Amazing way to share the story without overloading player with text.
If I would have to complain about something - the sound is a little bit missing. There is not much of it, though it feels consistent and fitting the game. The hero movement and the 1-bit style really reminds me of the HeartsBeast 1-bit godot course :).
Regarding playing sfx in cutscenes I think the easy way would be to have a cutscene node with script with function for each needed sound. Using the animation player node you can animate as well functions - adding sounds even to animations :).
Regarding the course - please, don't feel offended I completely didn't have anything negative in mind. I too drew a lot of inspiration from it and used (as allowed by the game jam) some general code like platform movement with major modifications: https://heartbeast-gamedev-school.teachable.com/courses - if you haven't used the course, I really recommend it - probably best game dev courses I have seen.
