I like the idea of having a game that does not use a player pawn and still is feeling like a journey. The concept is sound. The music does not really fit the theme. The riddles were too easy as the 1st and 3rd level seem to have the same solution. The text should be appearing much faster imho. All in all it was short but fun to experience.

You have some pretty good ideas here. I think the text and buttons could use a little work so you know where you're clicking, like maybe highlight what your cursor is hovering over. The soundtrack is very nice, catchy, and fits the game's style.

Interesting puzzles.

Here's a hint to improve the text animation: To animate textmesh pro without having the words jumping to the next line as you add them, it's a better approach to set the full text on the object and animate the maxVisibleCharacters property from 0 to the length of your text. This way, the text layout will be calculated from the beginning and it will look much nicer.

Good job on the game.
