ZER0ED is an action packed arcade-style math game about making zeros. Use Resources and fuel to get the Targets to ZER0 as fast and as often as you can. However, if a Target goes negative, you lose! The chaotic mania style of means each game lasts only a few minutes, randomization of the numbers means no two games are the same, and the lure of a "win" is only a few points away! ZER0ED challenges you to think quick and strategically as you plan your next tap. To do this there are some key gameplay features that force you to think not just about creating ZER0s, but maybe you'll want to end a number with a 5 to get bonus points or you'll certainly want to avoid ending a Target's Value with a 7 to avoid penalties. Additionally, as you score more points, the game's timers speed up forcing you to make your calculations even faster. The hand drawn backgrounds and simple sound effects and music add to the truly indie developer nature of this game. The entire project was completed by one person of the course of a few months of the time. To add more challenge and replay value to ZER0ED Game Center achievements and weekly leadersboards were added to the game. Can you get the high score? ZER0ED is a passion project designed and created primarily out of curiosity. It's the culmination of years of teaching myself to code, not because I had to, but because I wanted to. Thank you for considering this action packed math puzzler!
