The aesthetics are really nice and even remember a little of Ico.
The game is really hard… Spent a lot of time in the challenge to get the double jump. I think that some QOL changes can be made to make the first person platformer a little bit easier, like a shadow below the character to better show where the character is going to land without looking down all the time. I also think that some different type of world floor or skybox could be used to make it easier to orient yourself in mid air.
It was a nice world to walk around, the lego piece is a nice touch :).
