The name of the game let me have an image of a bird is flying and that it. The Bird flight cannot give me lots of information; it just reminds me of a flying bird. When I had just entered the game, there were two birds on stage and background. I just started the game immediately. Just use the “W,” “A,” “S,” “D” to play. I thought another bird was a robot, and I had to fight with that bird at first. However, I noticed that another bird just stayed there and had no response. Then the description of the game let me know that it is a PVP mode game. It impressed me because this idea in p5js is new, and I had never thought about this before. Use different interactions to control different items and build a PVP game. Here, this action causes the game differently because of another player instead of the game itself. The way is creative. It doesn’t give play lots of interaction, but let player give themselves lots of interaction. Besides, the goal also lets the game be funny; there is no win or lose. Just compare who gets the most points. The game reminds the “Fall Guys: Ultimate Knockout”; a lot of players play a map together. The only difference is that the map also gives players a lot of difference which make player die or delay. In other words, these difficulties make players kicked by the game because there is only one winner in this game. Besides, the players in this game also can use the map itself to make difficulties for other players as well. Go back to the Bird Flight, and there is no winner. It is just a relaxing game for two people. It has not that much competition or a clear goal. There is no dialog or some important background that need the player to understand as well. The “W,” “A,” “S,” “D” is easy to control the player, the attack method is also simple, for the other side “Up,” “Down,” “Left,” “right” also same as anther player which is easy to manipulate as well. The attached method is also clear. Both sides just have a purpose, just hit the other sides. The game also can put some strategy in the game as well. For example, just do not keep at the same height as the opponent or just attack. However, the map is simple, and there is not much hiding place for the player to avoid the attack. There is another interesting point is the bird is not a static picture, and it can move all the time. The wings are always moving, which lets the player feel the birds’ movement. At the same time, when the bird gets attacked, it will also show that the bird is hit. It is interesting; the response of the bird lets the game have more interaction with the game. Let players feel they are the “birds” and be a part of the game. It let the player feel more active and try to hit their opponent.
