Yes, I have started working on the sequel for The Adventures of Jumping Jim. The gameplay will not be too similar, the only thing about it that makes it a sequel is the Story, if you finished Jumping Jim on Normal or Harder, you may have noticed that It didn't really end. I did that because I already had the Story for the Jumping Jim Two already planned.

The reason for this is that It will be Longer and coherent, as in, one area connects to the next, not just random rooms as in Jumping Jim. and there will be enemies, so far more sprites will be made, more songs, more story, more Fun!
Jumping Jim Two will have:
Estimated Release... Sometime in the Future (2014)
