This surely was the project in which I tried my best to incorporate everything we have learned so far. Initially, I wanted to make a game that resembles an already existing game called, “Flappy Bird”, but I diverted my plan to render something different and original to a certain extent. The game’s goal is to fly out of the mysterious cave by avoiding blocks of flying lava. Prior to the instructions of the game, which is fairly simple, I gave a short dystopian background narrative that the player somehow ended up in the cave because things fell apart ever since 2020.
I made the instructions fairly easy. The player will be floating along the cave and the only way to maneuver is to use UP, DOWN, RIGHT (to speed up) keys to avoid the flying lava bombs. If you successfully get out of the cave, you will have to go back to the society, and that requires MONEY. Other people have also attempted to get out of the cave, only to be buried there. So you will pick up the coins that the previous adventurers have left behind and follow their legacy… If you fail, you will become one of them.
I used a few images of caves and rocks to design the game as follow.
Cave2
Rock1
Rock2
To talk more about the functionalities of the game, a player’s health decreases everytime he hits a block of lava. It will keep decreasing until your lives (initally out of 3) have fully depleted. You will then have to restart from the beginning. The placement of coins and lava bombs will be randomly assigned for every level. A very short song from PacMan will be played once you start the game and during the game a player will be able to hear sound effects when he hits a coin or a lava. You will see that there is a flashlight effect on the instructions page that was employed to create a more eerie and dystopian atmosphere.
Here is what it looks like:
