Hey! Interesting idea, bit obtuse but that's not necessarily a bad thing.
I first went in from the jam page and didn't understand the controls, taking a look at the game's page clarified that you need to press 1 in order to see the explanations for them. Once I saw those, you can tell there's quite a bit more to the game that meets the eye.
It can be difficult to navigate and tell in which direction you are moving (especially with low contrast settings). I eventually found the big shadowy figure and honked at it, though I didn't see anything happen after that.
Overall, I like that it's trying to do something different. You didn't go for a stereotypical game archetype and there's value in that imo. It currently lacks clarity, and I think it's something you could improve upon with more development time.
Btw, it's cool to see more people giving Godot a spin for this jam! Were the effects like the text warping at the beginning and the animated sea texture achieved with shaders?
