It's a rhythm game like a osu! only the gameplay takes place only using the keyboard.
At the moment this is the console version of the game.
Click on the corresponding displayed symbol on the screen to the rhythm of the music.
So far, one card is available for a 12 second composition (with the future possibility of betting on a much longer one), a points system and a bunch of terrible code, which I do not recommend getting into.
P.s. The composition must be located in the same folder with the exe file of the program, in wav format and its name must be music1.wav
