Wow, I have to say this has kind of opened my eyes as to how to lower the scope of a metroidvania game. I always think too big I guess, but it's given me ideas to maybe try my hand at a small metroidvania one day.
As far as the game, I liked the level design. Some of the platforming was particularly challenging but spaced out in a way that it didn't feel too frustrating. Although, I do think the game could have benefited from "coyote time".
I liked the art for the robot guy, he was pretty cute. And your music you put together is pretty impressive for such a small amount of time to put this game together. Great work, Olive!
