Ugh. It seems that some of the problems were just kept untouched from demos and videos.
Controls - Not unforgivingly bad, but worse than average. Unlike BS CotMs, the main character always tend to slip (like they're hesitating or having very slip shoes) when doing precise platforming. Even some of the castlevania fan games managed to completely avoid this problem.
Also there's some problems in air control, retreat half way in the air during a forward jump can be a serious challenge in bad ways.
Plot - Usual Inti Creates plot as always, albeit with an extra anime fanservice-y touch. Nothing really worth write home about.
Music - A bit worse than average. Whoever composed the music certainly lost the charm how the music in BS CotM1 was successful. (specially compared to the part of music tracks in BS CotM1 not composed by Michiru Yamane.)
Also there really should have a detailed sound effect volume control, the shouts during hops are really REALLY bad when repeated.
Difficulty - This game really is easier, easier than maybe even some of the easiest Classicvania titles available if it wasn't for the sometimes-questionable controls when retreating during a forward jump. If the air- retreating isn't a problem (or fixed by a patch) I'll retail-purchase the game ASAP then return to the game time and time and time again just like the old days.
Degree of Polish - For some reason the good choose chapter function in BS CotM2 is lost here. I'm really pissed off by this and it greatly discourages me from replaying the campaign again.
Another problem is the game's set price. If it's something like $12 to $15 for its initial price I would recommend it brainlessly. In it's current shape though, not worth it. This is some of the rare cases where Piracy really do justice.
