This was fun. Cool graphics and music. Controls are smooth (smoother than most Castlevania games, in fact, except for the Symphony of the Night lineage! :) ).
I beat the "boss" very easily, and managed to get the cheering sound effect, but couldn't figure out how to get past the first level anyway.
One quibble: it is a bit misleading how the player starts out with so many hearts, but falling on spikes takes away *two* hearts. This is somehow counterintuitive, because spikes are the first hazard we encounter in the entire game.
