Great game, even more impressive when considering the dev's age. With a very basic premise, the puzzles manage to be interesting to see and fun to solve. The many easter eggs and little touches (I didn't notice the boy spinning on gears before yesterday) only made the experience more pleasant. That BASIC loop was a bit savage though :P

My favorites were the basement puzzles. The "quantum entanglement" had already produced some great puzzles, but this opened up a whole new realm of insanity. A special mention for puzzle 097: did you play Stephen's Sausage Roll ? I would bet that this puzzle was inspired by the "Great Tower". Relatively simple to solve in hindsight, but absolutely terrifying the first time.

My least favorite were the pumpkin puzzles, simply because of how tedious they could get. The auto mechanic didn't do much to help in most cases. I still loved 082 and 085. 

My more general dislikes (purely subjective) was the idea of locking content (even if optional) behind optimization. However, even that was made sometimes rewarding by the interesting solutions it made me come up with, as in 037 and 057.

The game's objective flaws would be: 

1) The lack of an integrated way to keep track of puzzles not all-completed. I made sure to always get the token before moving to the last, but I wouldn't like to be the guy who discovers he's missing just one and has to check everything manually.

2) The impossibility to replay a puzzle after all-completing it. I always enjoyed replaying puzzles after finding a better solution, so as to better absorb the essence of what I did right, and it frustrating not being able to. It becomes a kind of counter incentive to getting the tokens.

3) The impossibility to change the controls. This is a problem common to many games, and which I feel is even getting more common with time. I could rant for a good hour about this LOL. Anyways, my arrow keys just randomly stopped working some time ago, as did my num8 key (it recently started working again though), so I had to use KeyTweak to make many of those games playable. However, my rollover sucks, and I cannot run northwest in this game. This made the runner and battery bits rather frustrating.

Aside from the puzzles, I found the island system delightful. I *love* when games do that kind of stuff. It was very well utilized, not relied on too much nor too little, even connecting it to some optional stuff. Perfect. I suggest you play "Islands" by Rosden (found here) and "Craequ" by Jonathan Whiting (requires Flash).

The music was alright. The Foreston theme was a bit grating, but all others were OK. Autumn island's were my favorites. For some reason, I also enjoyed the basement's "theme", which was really more like ambient noise, but it made me think that such lo-fi music would be generally better suited to ambient noise than melodies. 

That's about all I have to say! I'm dreadfully looking forward to the dev's next productions. Très bon jeu!

We're never getting a hint on the final secrets, are we ? Unless... The hint will be in the sequel ?!
