Hello! I was one of the streamers who took part in Feedback Quest, and I'm here to leave some comments I had while playing.
When I was playing, I felt there were some issues with the game. To start, there needs to be music or something during gameplay. It's otherwise quiet and awkward. I also felt like the screen shaking was too excessive. It shakes when you kill an enemy, and just on one enemy is shakes a lot. If you're killing multiple enemies, it can actually be a bit hard to keep track of where you are relative to other enemies. Finally, I did notice that as the game progresses, enemies require multiple hits to take out. However, the game requires you pressing the left mouse button over and over to keep firing. This can not only be tiring, but it could result in someone injuring their finger. I would recommend adding an autofire when the player holds the left mouse button down. That way, they can have a standard fire rate without the pain or they can choose to click themselves to fire faster.
