Firstly the game is beautiful and the design is fantastic. The ambient music/sounds are really good too. But maaan I hate the controls. It's like everything has a delay or it's just really slow to move/stop and feels super floaty and not very responsive especially once you're already in the air.
I really wanted to play it for longer because it's so cool but dying cos I can't do simple platforming jumps that you'd find in 1-1 in Super Mario because of the controls just annoyed me too much.
If that's your intended design/difficulty with the game then fair enough but it's not for me.
