hey, thanks for playing :) u can kill the bugs but that will result in a somewhat bad ending - there is a second pacifist approach to the game - it's all connected to the story (bits of it in demo - more to come). About the Metroidvania part - I would say it borrows some concepts of it like the closed doors that you need to figure out how to open and somewhat free approach to the level exploring - like you can go that way or the other
