Good Artwork and Music, but It's Barely a Game
At first I didn't know what in the world was going on. I saw two pictures next to each other and every time I clicked -5 would pop up on the screen. It took me a reset, and a few seconds to figure out this was a find the differences kind of game, and I have to say I was a little disappointed. That being said you need to let people who have never played one of your games in on what to do, because I'm sure a few people clicked a few times and said the hell with this, and moved on to the next game.
The artwork is very good and the music fits very well with the concept, so both of those are what carry this game. I can't say I'm a big fan of find the differences puzzles, so it was kind of boring and tedious having to look around for all the little things. Also, some of the objects were just really difficult to notice, especially the ones in that where just changes in landscapes. I found some of them difficult to find even with the wave finding thing. The more levels you played it became noticeable that a lot of the changes were in the same spots on the characters, so a tattoo missing on someones arm would likely be missing in the next image also.
I didn't really get the point to keeping score either. Granted it might of kept me from going crazy around the map just randomly clicking, but chances are the people who have the patience to play these types of games aren't doing that anyways, so the score seemed a little trivial.
It's definitely is a break from the normal games that come out, so you should be complemented for trying something different. I just feel that great artwork, and great music can only do so much for an average game. Good work though.
