I really liked a lot things you did in this game:
- The levels were challenging and there was good progression.
- The camera movement was also really smooth and enjoyable!
- The camera panning at the beginning of the level was cool!
- The light changing colours when collecting a friend was a nice touch :)
A few thoughts that might make the game that much better:
- If I found the exit the before collecting all the friends it would make me lose the level. I think it would be an improvement if you could continue the level to find the friends I missed rather than starting the entire level over.
- Add some particles to when an enemy gets killed and when you get damaged.
- I was getting one shotted in the second level. Not sure if that was intentional but I found it made the game a bit too difficult for me.
- Not necessary, but I think giving the player some control over the camera could help with seeing the enemies before they shoot you.
Overall, great job!
