We're not sure yet!
Honestly, We'd like to port Engauge to XBone, PS4 and maybe the Vita or Wii. It probably won't be a stretch goal since we're planning to port regardless of how many funds we get.
The only thing we're unclear on is how to get Engauge into Microsoft/Sony's stores. From a tech standpoint, we're already designing Engauge to be easy to port. We also went out of our way to design controller-friendly controls so the game should control pretty well on console.
Tl;dr - I can't say with 100% certainty that there will be console releases, but that's the end goal
