Was you health too low or had you already gone through many days alive? Well, by each new day, the dangers in the city increases by causing you more damage in a random percentage. To prevent that you must increase/upgrade your armor or your attack. In case of more questions, please, read the tutorial by clicking on the question mark button. Anyway, as soon as the Game Jam finishes, I will be polishing the game to make it or easier or harder.
Thank you very much for your comment! And please rate my game! =D
