About this project

I believe everybody (ok, most, not every) would have come across this Casio pocket calculator (model: MG-880) game called digit invader in childhood, if one was born before 1989. This project is an attempt to remake it. I know there are already a number of remakes out there but I have to say I feel they are not good enough because they loosely stick to the original game specifications, which I think is actually very important. I have tried my best to make it as close to the original game as possible, such as the speed, game flow, scoring and even the sound was analyzed using the Fourier Analysis function in Audacity in order to reproduce the sound with the buzzer.

Please see the demo video here for the short edition:
