Right now I'm settling for any engine as long as it's able to export to PC and Wii U and as long as the programmer has no issues working in it.
We have only a few people on the team right now.
Target platform we want to start with PC and hopefully through kickstarter stretch goals we can port to Wii U and/or 3DS via e-shop channel.
Right now only the concepts for how the game will play and control are made, we had something for an engine done but we've decided to start over from scratch back to square 1 because not a lot of progress was made and that one was like beating a dead horse.
There is no set date for the kickstarter right now, since I'm allowing the programmer to work at their own pace without feeling need to rush too quickly. However I'm sure we can get a demo done by mid 2016 if we work at a normal-ish pace. The content and Demo will have 1 playable character (Hopefully 2 if we can push it) and the demo will have 1 world consisting of a few different levels. I'd like the demo to be able to show how it's World map can function along with maybe 4 or 5 different levels.
