If you're talking about The Blank Game 1, it's finished, but not completely translated. If you don't have a way to translate Japanese or don't know it, it's still playable. Almost all the items that should work correctly are in English. All the items that look like skills were supposed to be skills, but they don't work so don't bother with them. You can equip them, but they'll act like hammers because that's how they were in Alternative Magic, wich is a Japanese game. Also, when you enter the sleep places, you might get a private action which is a conversation between the characters. I'm only letting you know of this because only some of them are in english. The following are in english: Milltown, Pamboo, Small Village, Exponents, Math Place. All the others are in Japanese so just skip them, and they don't relate to the game. Also, another thing you'll want to know is about the orbes. Their are orbes in the game that you can attack once and they'll be gone. In Alternative Magic, the orbes were supposed to stop you from progressing until you got the propper spell to destroy them. So, when I make the orbes so you could just attack them, only now did I realize that players could miss a whole bunch of the story. So, here is the list of events ware orbes shouldn't be destroyed until other times.
Between Exponents and Math Place: first, you will need to go to the side road between Pamboo and the Small Village, and do math to get light type magic.
Math Place: first, go to the ruins, beat the boss, then go to the main street after beating it. You can then destroy the orbe at the entrance of the Math Upgrade Cave.
Entrance of Math Upgrade: do not! Destroy it until you've completed the ghost ship! The moonlight tower is in the place with the town houses. I think that's all of them. Just pay attention to the story. It tells you ware you're going next, so search around the towns before leaving! Some of what the people say is also in Japanese, but no one gives you any skills or items, or advances the story, so you don't need to talk to them. Well, accept Trump in Exponents. Go ahead and talk to Trump and see what happens!
