I played the web version, sadly the joystick support isn't good, I can't use FLUDD and Ground Pound. When I read the first sign the game freezes, but I liked the game anyway. I played the "original" Mario 63 several years ago and I hope this one reach the complete version
=== EDIT ===
I just played the Windows version and is way better and joystick controls work great, but the first bug I mentioned still happens
