Hi, thank you very much for your feedback !
I'll adjust music volume.
The voices are not unsynchronized, I recorded multiples tracks to make the voice more "acoustic". I recorded it in mono, the delay you ear is just some milliseconds of gap between 1st and 2nd track.
Yes I will add a setup menu next week!
Is motion blur too high ? I really wanted to improve the game feel on the levels but if it makes you see unclear I understand it could be really boring.
Thank again :) .
Regards.
