Unity and Stencyl are both game engines used to build games with. I tried to get a programmer to port the game into Unity, but unfortunately the programmer I hired was not capable of making the game work. He gave up on the project and so I'm back to programming it in Stencyl which is the engine I'm used to.
I'm currently working on the next version. My patron or my Subscribestar has the live updates up at the moment. The live updates version is a version I have up during the development cycle where I upload new content as soon as I finish it.
Subscribestar is a bit closer to a normal subscription. patreon is per-post, but subscribestar is a flat monthly payment.
