Howdy!
I have to say, this is truly an amazing fan game of Super Mario Bros. Beautiful and creative!
If you were ever to make a full version or an update, it would mean a lot if you could add controller support to the game, along with maybe an Windows ARM64 or x86-32bit version of this game. Sadly I cannot play it since my ARM computer can't run x64 titles, but your work is just great!
Keep up doing all these good stuff :)
