I loved this game, it was a great puzzle game and has a fantastic art style that reminds me of nes titles like The Legend Of Zelda. The puzzles aren't overly easy or overly hard and provide a great intuitive experience!
Personally, it was a little annoying to move exactly a block and have the blending movement between because it provides the feeling of momentum which abruptly stops. But, that is just me being nit-picky, it wasn't that bad of an issue and honestly, I don't think that many people will care. Also, don't apologize for using a password system; it isn't a bad system and just created a more nostalgic feeling for me, which also made me enjoy the game some more!
