Challenge 99 is a precision platformer where your goal is to guide a nanoball through increasingly difficult levels in an attempt to escape a simulation. I made this game to test your perseverance and to push your ability to overcome seemingly impossible obstacles. If you can make it to the end of the game, you can definitely call yourself a master platformer. What the game offers: 99 unique and creative level designs. 8 different abilities to master. A practice mode that will help you prepare for the upcoming obstacles. A race mode where you earn ranks by beating fast time goals (with a ghost feature). Tough to earn in-game achievements. Hidden easter eggs and secret collectibles that invite some exploration
