I am a huge Galaga fan so I really enjoyed playing a couple rounds on Free Bird. A few things that I noticed right off the bat is that once you get past round 3 on level 2 it continues to count upward. So it say level 2 round 4, round 5, etc. Also when you do eventually lose the game didnt give me an exit option so you have to kill it with the task manager. Im sure this is being implemented just wanted to mention it. As for the player movement I actually think it works very well. If you do decide to implement the ability to move up and down I think the entire feel of the game will change and youll have to change the way enemies spawn into the map. As for the projectile speed I thought it worked well but I did notice that the fast blue projectiles only took off after the enemy in front of them had been defeated. Maybe I just didnt see it correctly but if this is the case I would allow the projectiles to move from any space on the board at any time. If the fast ones have to wait in order to take off then it makes them very easy to eliminate. I think the player health is perfect. I do think that the enemies do a good amount of damage as well. Taking 3 or 4 hits seems like the perfect amount of life for the player. As you move up in level it would be cool if you were given more life based on the difficulty of the level. Or maybe increment the life by 1 every 5 levels? The only thing that I really thinks needs improvement is the HUD. It didnt really fit the style of the game overall and it was blurry and difficult to read for me. I like the set up though as it is like a classic arcade game. Great work guys!
