Hello!
Every comment is important for us. We are sad you did not have a great time while playing our game. But thank you for taking some time to explain your feedback.
Controls are taught within the game directly, you have posters and signs in the background, which explain controls in the first three rooms of the game.
You do not need more to reach the end :)
As for the physics (similar to our controls) we wanted to implement an airy gameplay. Philemon can reach important heights and takes time to fall.
It provides time to adjust your inputs.
If you play SYMPHONIA again, let us know how it went.
Cheers,
