As of right now, there are only two worlds in the game. They are:
In this world, you start off simple... but slowly gain your way up, as you get familiar with the game!
When you reach at least Gold rank in all Green World Levels, you unlock Green Robo!
In this world, you get to know about fun new mechanics which alter the way you play in levels! From gravity strengtheners and weakers(shush the english is goated here) to speedsters, these mechanics will test how well you can adjust to the abnormal.
Sadly, no. I was planning to add ice world, but I lost ideas on what to add for levels content... but maybe one day the idea can come back... who knows...
