Interesting but very short
I fully enjoyed playing this game with the wonderful music and the great voice acting. It probably was why I felt very startled when I realized that the game had already ended. It is a very short game as it seems to set up for the sequel (which I have heard is much longer). Despite its length, it is still an entertaining and really beautiful game and definitely a good game to play particularly if you plan to continue playing (and I definitely want to). Outside of length, I found little to complain about other than the fact that you will have to wait for your character to walk across the screen rather having a "double click to change scene" function.
Is it worth the full $6.99? Maybe not, due to the length, but some might find that the quality of graphics, music, voice acting, and just being an entertaining point and click makes the game worth it. But if you can get this game on sale, I definitely would say its well worth it.
