First of all I really liked the visuals (cutscene and all) I did like the story too. The voicelines were really nice. I loved the different voices you made. It clearly shows how much effort you put into the game.
On the other hand I felt like the shooting had no real feedback. It felt a bit unresponsive and I didnt know if I hit or missed at all. A lader beam, Hit marker or something like that would be great.
Overall a very solid game. Good job!
