It does look really nice, but it seems a bit too "floaty". It's hard to explain, but something seems off. They should try giving a bit more gravity to movement and jumps and stuff. Still might be worth checking out if it comes here.
Doesn't really look much floatier than the actual DS Castlevania games, actually. Looks like a fun little game, perfect for the eShop. I especially like the offbeat art.
The weird gimp dragon makes me a bit sad, though...
