I finally finished up Trine today, doing the last half of the game in one burst. The levels started getting harder again, and a lot longer, but they weren’t too difficult and I picked up enough new abilities that solutions weren’t so hard to find (especially the floating pyramid).
The last level seemed rather unfair, though, since it involved a timed ascent up a tower, with obstacles spawning in the way. I played the rest of the game at a fairly casual, deliberate pace, and it was rather frustrating to suddenly be forced into a fast, frantic event with little margin for error. I eventually beat it with the thief after a good dozen or so tries, but it wasn’t really that fun compared to the rest of the game.
And then to add insult to injury, it didn’t give me the achievement for completing the game…
