Not bad. Not amazing, but not bad. A decent Castlevania lookalike. Couldn't understand that character screen with the opening and closing cowl and the controls that aren't actually in the game and it took a few button presses to get the game to start. Seemed like that was a character select screen, but there weren't any other characters? That first boss is a real pain with the limited character mobility and how hard it is to hit things, but I guess that's intended to emulate the feel of early Castlevania games.
