I'm trying to get into Alex Kid in Miracle World, but the "one hit you're dead" thing and the fact that you have to do a secret button input if you have the coins in order to continue is really off putting. There's a hack that just has infinite continues enabled called Alex Kidd in Miracle World 2, but that's a total conversion. I'd like to see this done for the base game... and all the other Alex Kidd games as well. I've not played them all but I've played Miracle World and Enchanted Castle, and it's the same story with both so I assume it's the same for the rest of the series.
...Also, it would probably be difficult...but some... ANY kinda tell for the bosses and what hand sign they're going to throw out during Roshambo... A subtle hand waggle for paper, a defensive stance for rock, ANYTHING
