Don't know why I assumed it would be so finite
I solved enough of the puzzles in Infinifactory's last level to look ahead to the game's ending -- or, what I thought was the ending. Apparently it really just unlocked the second half of the game.
I mean, I'm not going to complain about more puzzles, so long as they continue to present new and interesting challenges. But I am starting to feel a bit worn out. More so than in SpaceChem and TIS-100, Infinifactory's solutions require a considerable amount of work to implement -- due to having to manage moving parts and equipment in 3D space.
And as the puzzles become more complex, a surprising challenge has emerged: being able to move the avatar around the puzzle, and reach equipment you need to manipulate. I'd much rather that the avatar had no collision physics, so I could more easily debug my increasingly tightly-packed machinery.
Also, I was really hoping to close the book on this and move ahead to Shenzhen I/O. Oh, Zachtronics, you spoil me so.
