I think I got it from somewhere like "shockwave.com"? - Source: Reddit / 2 months ago
Other details: From last I could remember, the game was on the shockwave.com website as late as 2012, but as of now I have no idea what the title is. My best guess is that the game was called konpira and mentioned samurai or slam in the title. - Source: Reddit / 17 days ago
