Really cool entry, I dig the chill vibes. Echoing some other comments, I think the player felt out of place visually, one random idea would have been to make them out of contrasting particles.
While I love the standard metroidvania upgrades, I really like seeing other takes but I would have liked more variety in the lock and keys. The description on the main page is really making me think about this; I think the hallmark of a great ability is that is has “frequent utility”, which is why double jump and dash are so good, they help in combat, regular exploration and simply traversing more fluidly/interestingly/faster. Put differently, they change how you experience the world. Now I’m trying to thing of crazy things like adjusting the focus, some rooms have different focal lengths and you get the ability to adjust is to make them not blurry and reveal hidden things.
The depth aspect was cool, I’ve had a similar thought so it’s good to know it’s successful. Great work overall!
