Thank you for playing the original version too!
Lots of players prefered the original over the RPG Maker version, I guess the circle battle system is more fun and the experience is more enjoyable since HP values are visble (even though Game Over is very punitive since there is no Retry).
It was supposed to be ported over but hehe I couldn't manage to recreate the circle battle system in RPG Maker MV unfortunately...
Yes you listed all the differences right!
