Marble Apotos City is a hack made by aglab2 for Arthurtilly's 2nd Hacking Competition. It is a fast paced, openworld-style hack where the player can choose whichever route they want to collect the Stars in any order.
Overview[]
Stars do not warp Mario out of the level, and the majority of the "levels" are located in the same course. Crossing the threshold between "levels" will prompt a music change to signify the switch.
The lives counter has been replaced with a new coin-based function. Each time Mario dies, he loses a set amount of coins. If he doesn't have those in hand, then the player is given a Game Over.
A customised battle with King Whomp is available on the other side of the course; he is now extremely large and sports a bizarre formation on his back. Now, whenever he falls flat, Mario must wallkick up the formation on his back to reach his weak spot. The duration of time he stays flat has been extended to allow for this to be possible.
