Trine is a great, fun game! And I believe there are three of them. I only got to a level in the first game that I thought was very near the end, but involved a game of “stay out of the lava while climbing this tower in bullet hell”, and I kinda left it there. I recall it being very funny, with clever platforming.
That’s where I stopped too. I think it was last level. Tara and I were playing it co op, and it was freaking awesome for me to be doing wizardy summoning planks above us to protect us while she was rangering around.
