Co-op based games like Bird Fight are very interesting to me because it allows the opposing player to take the place of the computer in the discussion of interplay. While elements of computer interplay can still happen the predominant form happens between players. If no elements of randomness are added into the game, it could be argued that the game revolves around 'pure skill' in the sense that if you are good enough at the game, you can beat anyone. This attribute can be a double edged sword with regard to a player wanting to continue playing. If a player consistently plays with people who are better then them, then they might feel like they have no chance and stop playing or have a negative experience. However, if that same player dedicates themselves to learning the game more and becoming better, it can be a very rewarding experience to win in 'pure skill' games. To me, it didn't seem like there was any interplay between players and the environment/computer which could be an intentional design choice. However, if interplay between computer and player was to be added, some ideas I had were making it so the bullets bounce off the walls a certain distance, or having enemies appear that can reduce the lives of either player, etc. There could even be the 'pure skill' mode with no computer additions and the game mode where other interactions can happen. Another comment mentioned Smash Bros and I think this example is very similar. In Smash, there is the options to turn off random item generation for a 'pure skill' matchup vs a more dynamic matchup with randomness. I think that the control scheme gives a direction towards the design of the game as well. Both players able to control from the same keyboard while looking at the same screen, it removes any 'screen peeking' that many games have when playing on one screen. This is in part due to the fact that the game only takes place on one screen, but I think that it is still something important to recognize because it removes yet another element in any perceived unfairness. Aesthetically, the game is a light hearted cartoon style reminiscent of Looney Tunes art style. This makes the game appealing to a wide range of people from young to old. The rules of the game are fairly straightforward and simple which also appeals to beginner gamers and experienced gamers alike. The simplicity in the objectives and rules is once again consistent with the idea of the game being based on 'pure skill'. Because of the simplicity, players are allowed to direct most of the focus at getting better when facing different opponents. They can develop different strategies based on player behavior and move into the mind game territory within versus type games. In conclusion, I think that this game has a lot of simple fun that can turn very complex depending on who is playing.
