Thank you for the feedback!
Could you tell me at which point did you start getting bored? Would it be better if I had fewer levels?
Don't get me wrong, the game is good, what's the most important in gaming is functionality, the rest is up to the taste, some like more levels, some few, it's not bad, rather subjective. You should be proud of your game. Overall I enjoyed playing it, just the music was little off and the theme did not match with me, that's it. Ending was superb. Good Job!
I know you are not offending, I am saying that constructive criticism must have positive outcome. Your game was good.
Yet, if you want advice, I would recommend color change, maybe adding texture, maze part and matches was great, but, maybe add a special match, which can light entire room for only a second, would be fun. You can also add a book, which appears and disappears, so it's little challenging to find it, I mean lots of ideas. The game was not annoying, not at all, just little repetitive and not scary. That's all friend.
