Hi there, first of all very nice visuals and sound. Good job!
1) no.. it seemed too long (but i'm not really a gamer)
2)it seemed ok for me even if i played for a few minutes
3)ambient in general is very well done! I felt like I was in a alien like maya
4)for my taste it was a bit slow pace. but i guess that's the point with exploration games
5)I would like to have a weapon and some enemies.
6)all good
7) no bugs
I did really like it. Will play it again and let you know if i manage to finish it!
Bests,
M
