Castlevania series. Despite being a Japanese indie game, it actually comes with English and French language options, which is pretty nice, although the translation is... lacking.
Despite looking a bit blurry, Reimu animates pretty well. She has a smooth transition from left to right, and there are lots of frames in her walk cycle and attacks, making it all look rather nice.
Castlevania! Just like in Castlevania, these Mermen like to suddenly jump up onto the bridge out of nowhere.
Castlevania. The maids only take two hits, so they're waaaay less annoying. Also, the chandeliers on the ceiling fall down, but you can avoid them just by sliding.
Castlevania fans, those stairs are just part of the background. You make your way up by jumping/flying instead.
Castlevania 1 Block 5, with the long hallway filled with Axe Knights and Medusa Heads. For some reason, I haven't encountered an equivalent to the Medusa Heads in this game, so this hallway is really REALLY easy in comparison.
here. Like I said before, it has an English option, but the gameplay is just basic Castlevania stuff with flying thrown in, more or less.
