A very good game, I have been looking forward to the FC version of Mario. Like the Contra, two people can fight with the screen, instead of two people taking turns to replace it. After 18 years, the dream is finally realized here. I hope the author can formally complete it. Game, add more levels. Suggestion: If you can take a risk, you can choose 1p and 2p without physical collision. I look forward to the official version of the online steam, add more language options.
