This is what I'm working on now: Hexoshi, a free-roaming game inspired by Metroid (or rather, Super Metroid). I'm doing this one differently than ReTux. Rather than trying to fund it all at once, I'm doing it in milestones, and Milestone 1 is what is being crowdfunded.

Website is here:

And the crowdfunding campaign is here (hosted by CrowdSupply):

As I'm writing this, the campaign is not yet launched, but it should be launching in a couple of days if everything goes well.
