The challenge was:
The first person to perfect all 72 levels in Thrusty Ship will win $1,000 from us. But nobody was able to do it. Is Thrusty Ship the hardest platformer out there? Time will tell.
In the meantime we've been working on an expansion for Thrusty Ship. It will have a new world, new levels, new ships with special abilities and a new game mode. We will release it on January 23rd, for Thrusty Ship's birthday.
Thanks for a great year, and look forward to future updates and challenges.
