I'm surprised this is first GBStudio game I've seen in a GB centric game jam like this. It seems like you had a lot of ideas for this one in terms of a narrative. I think the game is, in general, pretty hard to read. It's difficult to tell what is interactable, solid, or what exactly damages you.
The combination of enemies flying across the screen and the constant background noise sort of made me feel like I was going insane lol (I read you're other comment about that. I've never used GBStudio so I have no idea what goes into SFX/music for it).
