Thank you Michaël.
I wrote down some thoughts about tutorials and about suggestions which I probably wouldn't find disturbing in Bientot l'ete.
Personally I'm embarassed by the approaches a-la-gamification to tutorials: "Congratulations! You memorized your first phrase!". On the other hand I like it when the author takes the disturb of guiding me through the uncertain first steps, if he/she does it both respecting the player's intelligence and the his/her own work.
I particularly enjoy a tutorial when it integrates seamlessly in the gameplay, like the first minutes of Bioshock, or when there is a separate introductory part both creative and in tone with the game, like in Dinner Date's training intro.
Given the minimalistic nature of Bientot l'ete I feel that adding an intro or some new gameplay elements to guide the player might be out of place and artificial.
Personally I wouldn't mind to find writings in overlay which suggests the main mechanics, provided the style (also v) fits.
In The Path for example I liked the style of the mother's recommendations and also that of the Girl's thoughts: I perceived the as an integral part of the world, so I never felt like "Ok now I stop playing and start reading".
Maybe because of the literary DNA of Bientot l'ete something like this might resonate with the world.
I wouldn't see the need to explain the quantitative details (like the number of store phrases is 16).
I prefer when the suggestions feel indirect, better beeing intrigued to reach the shoreline instead of beeing told to go there. That also would reinforce the feeling that I'm free to wander and play my way, even if the collection mechanic is quite precise an so it needs to be learnt.
Generally I feel a bit anxious when a tutorial presents me several goals to be achieved, as a list. Maybe it's just a problem with my short time memory, or the fact that it starts to sound like duty
Continuing the overlay writings example I'd prefer to see a sentence gently inviting me to the shoreline, then another about "stopping to remember" appearing as I stumble on the first phrase, then beeing reminded of the cafe only after few sentences are collected etc...
One coincidence: the night before playing the alpha I dreamed about a strange afternoon, during which the sky became suddenly dark.
Another recurrent dream of mine is that I look at the stars at night and they slowly start moving... so I can't but love and feel so immersed in your "space" twilight
