About Constant C
Constant C was developed by International Games System, Co., LTD.. The release date was March 10, 2014. The genre is characterised as Action and Casual and Indie.
In the year 1905, Albert Einstein published the theory of special relativity, suggesting that nothing could move faster than the speed of light. What if any mortal could break that constant? Stretch it beyond its limits? Would human beings finally be able to find a way to cheat death and win over immorality? Or is it Chaos that follows the manipulation of time and gravity? Constant C is a 2D puzzle platformer with two core gameplay mechanics - Gravity Shifting and the Time Field. Using these two mechanics in the game, the player controls the momentum of various objects to complete each level. Dive into the world of Constant C, where rules of fundamental physics no longer apply. In a space station far away from Earth, mysterious events have triggered the distortion of time. Journey through the game as a lone robot, who uncovers the truth behind the incident step by step, and finds the purpose of his own creation. Feature • Gravitational Shift + Control Time Flow = Momentum Manipulation • Over 100+ mind-twisting levels • 2D skeletal animation with cute character designs • Created a unique futuristic, mysterious atmosphere with beautiful lightning • Kickass soundtracks Gameplay Gravitational Shift Momentum Manipulation

Where to buy Constant C cheap

On that same baseline, official stores start at $9.99, so the keyshop route saves $2.25 on this title. That saving comes with a trade-off: keyshop listings are resold keys, and a listing marked as a gift is not a standard key. The key type column above tells you which is which.
Feed update times differ by store. Confirm the current price, product type and activation region on the store page before completing the purchase. Our comparison methodology explains matching, ranking and checkout-fee limitations.
