Hello,
A Mario-themed game where you need to survive is interesting and simple, which I like. I played all the way to the end, so I guess I can survive! lol Anyways, I figured out how the game system works in order to survive, which made the experience a bit repetitive even though it never gets old to control Mario (I think you captured his movements very well here). I suggest having rooms/areas (arena-style) with waves of enemies rather than a scrolling level for a survival game.
Thanks for sharing, I really enjoyed playing another Mario game!
