I love this game! However, I have to note that the undo function is VERY buggy. I often cancel a connection and information ends up in a different place from where it was supposed to be. It's a pity that an otherwise amazing game should have a bug like that. Please fix!
There's a small bug: If you turn into a werewolf immediately after you get the cigarette and before you turn around, destroying the device, then you end up without a cigarette.
Some levels of the coin mode are clever, requiring you to solve the level in a certain way (for instance, "Double Curve Shot"), but others are just annoying. For some levels with very many coins, you rely more on luck than precision to get them all (for instance, "Move It").
This is a fun and clever puzzle game, but it was very, very wrong to try to make it "educational", since this is not the developer's field of expertise. People have been finding lots of scientific mistakes and they have been voting it down because of those mistakes; and rightly so, as the game does not fulfill its stated purpose to educate. It's a pity, because the levels can stand perfectly well on their own, and the game would get better votes as a puzzler.
I see many comments complaining about the apparent lack of a mute button. There are in fact mute buttons in the pause menu, but people seem to miss it. Perhaps it wouldn't hurt to add the mute buttons to the main menu as well...
It loses my progress every time I quit (on Safari at least). Not a big problem because we can access every level from the beginning, but I'd like to keep track of how many levels I've done.
I've been playing with the mouse lately, to get my touch number up. Mouse controls are not good. Columns and rows should light up on mouseover, not on click (it's kind of useless information when I've already clicked the square). Mouse pointer should change according to whether I'm filling in or crossing out. Switching sound should be different according to whether I'm switching to X or to fill-in. As mentioned by other people, it needs a stay-in-row or stay-in-column function (according to which square I've clicked second) - you could make it unlockable, though I'm not a big fan of having to unlock these things, but this is the spirit of the game I guess.
The way discounts work makes no sense. If I want to buy something that costs 100,000G and I'm wearing both discount badges then I only need to pay about 87k - but I need to have 100,000G otherwise I'll get a "not enough money" message. When I do pay, I get the discount, but why do I need to have the full amount?
Wow, you keep getting nightmare-related stuff spot-on. The list continues... Sleep paralysis (complete with a Mora-like halucination)? Check. Walking back into a room you've been before only to realise the location has changed completely? Check. Inversion of a go-to reaction to take away any feeling of security (if you run, you DIE - you have to stay perfectly still while the monster's there)? Check. I have to say though I wasn't as scared as with the previous ones, and this one seemed easier and shorter. Still, 5 stars from me.
