This is a great series.
Alright, so far I have done 1, 2 and 3. The longest stumper so far was the first. My favorite puzzle so far has been Einstine. I was just happy to have puzzled that together myself, it was quite satisfying.
Alright, so far I just want to say that this reminds me alot of the myst series. Not essentinally just because one is using the mouse to solve puzzles, but because there is this eerie emptyness that follows this unique world. You enter the games as a player ready to solve the puzzle, but halfway through you gain a feeling as though you are accually lost in a maze. The use of music was well choosen to create this effect. I have to say the third one was somewhat of a siapointment. I didn;t feel as though I wasin a place of importance or immersed in a wold. That allowed me to become detatched and remember I'm just a player playing a game. So I'm hoping this style was just a one time thing.
I am yet to move on to #4, but already I am hoping you will release an acual PC game on my local EB games shelves that has a few days worth of gameplay. These games are few and far between, but they show that video games aren't nessisarily about violance and gore. That a game can accually teach people logic skills and to keep an eye out for connections between things. Easily usable skills in life. You have done a great job so far, I hope it continues.
I'm off to play #4.
