Visual
1 ... Add little more movement than flickering BG
2 ... Add transition to main game
3 ... very unique looks
4 ... main menu may be little more animated (now is only static image)
Sound:
1 ... There is no sound when talking to grandma at start, except when talking (I see potential in this talk sound).
2 ... bg OST/sound pattern -> it feels repetitive
Controls
1 ... Test full screen -> mouse goes out of screen & you are unable to change direction.
Design:
1 ... if you lose control of spaceship/airplane -> you have to restart game cause controls are hard to control & you do not know where you ended.
2 ... check this out: Airline pilots on 30k feet / 10 KM lose feel of direction, cause all around looks the same
(this happens in your game)
Bugs:
1 ... Different scene load lag (1.5sec)
2 ... entire ship bounces if you hit space object
I ran out of 10 mins before checked all context (I haven't found city).
