Your page says you're Japanese and can't understand so I guess this crit's for the birds but:
Loved the art/juice/audio, all really high quality.
The core mechanic is really good and has a lot potential. I'm not sure if I got to the end or it hung but it was probably a blessing in disguise as the one on one levels had already gotten a bit stale, I'm guess it was due to time constraints but your mechanics could make a really good puzzle game in the vain of nova-111
