An actual good review.
Alright, I may be a little mean about this, but this will improve.
Graphics: 8/10. The graphics were nice for the vampire puzzle, but the bunny one felt like it was lacking. So I would give this a 8/10
Audio: 7/10. The music is repetitive a lot of the times. It kind of gets annoying. You should think about switching the music.
Voice: 9/10. The voicing is okay, the amount it had at least. The rabbits talking could have been better though.
Concept: 10/10. It may seem like your everyday puzzle at first, but however this puzzle has not only a story, it has the pieces moving, adding difficulty! Great concept.
Gameplay: 9/10. The game play is really good. The only reason I gave this a 9/10 is the typos. You had a few typos, such as the newspaper that the vampire is holding, you spelled a few things wrong there, but still very nice gameplay.
Difficulty: 8/10. It's harder than it seems at first. But it is very fun to play. The difficulty won't go into final score, but it sure was hard at times.
Replay: 10/10. There is no reason you wouldn't want to replay it. You can make your own puzzles or follow story mode again. Either way, this game is timeless fun.
Overall: 8/10. The main factors were graphics, audio, voice, and gameplay. The graphics, like I said, could be better, but they were quite nice as they were.
The audio was okay. The music got repetitive sometimes, but that is fixable.
Gameplay is almost flawless, except the spelling errors which you should fix if you do a sequel. Voice acting is very good, except the bunny talking, which should be a little better than it was.
Very nice flash, I look forward to a sequel.
