It was pretty annoying how luck-based the whole game was. Every planet is just as likely to have a powerup as to be completely useless, with no hint as to either nature. Planets are connected to each other arbitrarily, and worse, some are dead ends (again, with no indication or justification). Worst is when a planet is both unremarkable AND a dead-end, for you are forced to waste precious years on a pointless mission. And frankly, you shouldn't age at all during travel time. I mean, do they honestly not have cryonics in the age of interplanetary travel??
Puzzle mode is one of the most sadistic, mean-spirited, brutally unforgiving games I have ever played, and that's if you've already completed normal mode. If you choose puzzle mode first, then may Santa Claus have mercy on you. You poor bastard.
Sorry, I should have been more clear. I know it will always be a properly constructed puzzle and never repeat a number in any row, column, or square. What I mean is that the random revealing of numbers at the start makes no guarantee that the puzzle is beatable though logic and deduction only (i.e. without hints).
By the way, does anyone know where to find the tokens? I've found only 2 so far: one in a pot without plants to the right of the portal to the garden, and one on a ledge in the room reached via spiral staircase.
Small bug: if you complete the path that connects the two left-side portals (of the set of four portals in the garden), you turn off one of the two portals, walk through the portal that's still on, and take the path all the way around to the other portal (which should be off), it will still be on, and you can use it to return back to the place with four portals, although it will turn back off when you walk through it. I think it goes without saying that you missed out on a clever secret by creating an area that was only possible to reach by walking through a deactivated portal.
