Hi there. little crazy but i had a couple ideas for romhacks, these Flash since are based on two Mario Flash Games, since Flash support ends in 2020. I got inspired to post after seeing a romhack of Super Mario Bros.3 which had the other 4 games in its library.
One was for Mario The Star Catcher, a puzzle game where you collect stars, dodging obstacles as you do so.
The next was Super Mario Crossover: Super Mario Bros. 1 but with multiple characters like Mega Man, Bill Rizer, Link, and etc.
I cannot program for the life of me and my technical knowledge is incredibly limited, and i don't know if this would even be possible, but i figured i'd let the idea out there since these are interesting games and its a shame they're limited to Flash
