This program is a Covid-19 version of whack-a-mole called put-on-a-mask. The idea was inspired by an online game that my friends and I played during the pandemic called Covidopoly, a Covid-19 version of the board game Monopoly. Like this game, I wanted to make some light out of this dark situation we are in a make a fun, easy, time-passing game that will (hopefully) keep making you play until the pandemic is over.
To play is simple: the player must put masks on the viruses as fast as they can. There will be a total of 4 viruses on the screen at all times and once a virus is successfully clicked (accompanied by a “pop” sound), it will regenerate in a random color to a random position. If the player misses or takes too long to click a virus, they will get a strike– an accumulation of 3 strikes will end the game. The virus that was on the screen for too long will disappear on its own and regenerate in a new random color and position. Every 20 points, the player will level up which makes the time it takes a virus to disappear on its own shorter.
If I had more time, I would like to add more complex elements to the game like making the viruses move around, add more viruses to the screen after a certain amount of levels, or add more clickable elements for bonus points or strike reductions.
