Fair enough. Thanks for playing.
1) "It didn't fit the theme in any way"
- The theme was left open for interpretation. The game requires you to re-play the two phases of the game; making solving the puzzles steadily faster. It is a bit abstract, I'll admit.
2) "The character moved really slow"
- I didn't account for speed optimization when deciding between the two doors. I felt it important for the narrative to read each of the signs. I think in the future I can definitely speed up the character to make the redundancy less grueling, but my 3 hours was focused more on making the game playable then in optimizing the fine details.
3) "I didn't see any other way than guessing"
- Sign 1 and Sign 2 are meant to encourage the player to go back to the maze to determine how to progress at the doors. I'm sorry this wasn't more obvious. In the future, perhaps I can put a text-tip above the first door that says "to the maze" or "to the wisps".
