I loved Town of Passion (ToP) and though I've barely gotten into Kingdom of Passion, I already got a couple big laughs and the first puzzle was both unique and challenging. Usually RPG maker puzzles are just pushing rocks and boulders, but this one required more strategic thinking as you had to line up reflectors. Also, I like that sometimes you can shoot enemies now, but they didn't do completely away with ones you can only sneak past. This game seems to keep the best of ToP and add some very substantial improvements.
The women's bodies in ToP were cartoonishly exaggerated (not a criticism, it's part of the fantasy) but in this one they're quite a bit more exaggerated, in some cases it's too much for my tastes, but if you like that then this is perfect for you...so far. :-) However, given the quality of Siren's previous work on ToP, wherein the game was so good, the aftergame was better than 99% of RPG Maker games, I have very high expectations from them.
