Johan Peitz's "Super Mario Summary" re-creates all the levels of the original game, condensing each level to its essence with a single screen:
A Super Mario Summary is my entry to the 23rd Ludum Dare 48 hour game development challenge. I tried to recreate every level in the original Super Mario Brothers game, but on a single screen each. The result is a puzzle platformer where you need to combine reflexes, timing, and clever thinking to succeed.
To get the highest rating on a level, you need to take all coins and hit the top of the flag pole. Good luck!
