I gave the game yet another try, but... Let my say it this way: Natural calculus and first order logic is also very interesting, I did a lot of formal brainteasers in my university days, but now I am a lot more into applied logic, Clausewitz style.
On the other hand, I told a few people about Tidalis, and those who actually tried the demo are all very excited about it. It seems it has this addictiveness built into it, where ppl wants to play just one more game, and after that just one more etc. for hours. So when the word gets around...
And congratulations with the reviews and all the attention you have got so far, it seems Tidalis gets coverage almost everywhere on the internet, at least those places that I visit. I believe you have hit a gold mine with this game.
