It's cave story with a dedicated hug button. 10/10, game of the year!!!
Okay, in all seriousness, this is an adorable and fun little platformer. The whole window splitting idea is very interesting, although it does not provide much for the gameplay other than blocking your view of the entire level, I think this concept is worth exploring further if you want to. I do enjoy my time with it even though it is short, and the controls may feel floaty, but to a person who played cave story this feels right at home, you can nailed an entry despite working within just a day.
