Blame Super Mario, which I based the controls on for those who are familiar with said game.
Im not blaming anyone xD i was just kidding but maybe I didn't use the most appropriate words, my apologies.
Now that I know you've based the controls on supermario games it makes sense.
But even with that I would say that those controls made sense on old gamepads, because of the position of the buttons, but on modern gamepads it's a bit uncomfortable (at least for me) even the new supermario games have updated that.
Anyway, as I said, congratulations to the team, the game looks amazing and I like the idea. Keep up the good work ^^
