They're wrong. Your game looks nothing at all like Secret of Mana, hahah!Thanks a lot man! I need to play secret of mana at some point; I've had a couple people say it reminds them of it.
Not that that's a bad thing, or that it should keep your from playing Secret of Mana. It's one of the best games ever! Play it with a friend or two, though. it's definitely meant to be a co-op experience. =D
Your game is reminding me more of Ultima and other oldschool western RPGs more than anything out of Japan, though. Which is very cool in its own way! Your dev process itself also feels super Western to me, starting from ridiculously solid tech and creating a game from it, instead of what seems to be the Japanese way of starting more with art and story and concepts and building the tech to support it.
....Basically, this is a very unique devlog, and I'm having a lot of fun watching you build this game. =)
