! MARIO BROS.

Description

Published September 2000. Also known as ! MARIO / ！マリオ for its abbreviated usage, and "Exclamation Mario" if you're saying it out loud to yourself. Can you find and beat World "!"?

Some of Docokalaki's personal notes: (translated)
"1. With a savestate-type difficulty so great that self-proclaimed "super players" may struggle.
2. A world-class attract-mode demo that will make you cry. You'll know it when you see it. (This technique is not necessary for the game.)
3. You'll often have to retain your Big/Fire state where needed.
4. The use of Piranha plants can be considered unusual.
5. Not many pipes to enter.
6. There are few checkpoints.
7. There are good to bad obstacles, from cleverly-designed ones to plain lazy.
8. There is a lot of nasty level design, which reveals the author's poor aesthetic sense ......
9. Not only does the author have a poor taste in aesthetics, but also his ingenuity in trying to prevent every foul play by super players.
9. Many enemies have the "!" mark on them.
10. Relying on my own ideas as much as possible, without being influenced by many other works being released at the time, I made this hack to be as original as I could.

It's a lot harder than I originally planned because of my tendency to get carried away.
It requires a lot of knowledge of Mario's physics in-and-out, not to mention some techniques and minor glitches."
