Oh ok
I hope you had fun then ^^
Anyway it would seem that I can't do what I wanted (character in a sphere, nice keyboard gameplay, etc), so in the end I will probably have to give up with this idea for the moment, until the next update(s) of VS...
It's a shame, I have good ideas of projects and motivation, but I always end stuck because of my lack of knowledge in game engines.
I will simply continue my game TWOTIO (the one I made during Adventure Jam) as initially planned (that is to say a classical point and click adventure), I think there is already a good potential.
