I have tried it now, it's quite fun, the outer appearance of Satori and Koishi are lovely and changes appropriately depending on what the field shows. And holy crap on the 3rd level's pre-stage cutscene. Also, Hinacle, try to adjust the controls to your liking.
Somehow reminds me of a flash game I played (Talesworth Adventure I think) & an old Windows game called Rhapsody (a 2 player vs game where you input codes [(cardinal direction + distance)(cardinal + distance), etc] to reach your opponent before he/she does - kind of like battleship)
