I'm making it in XNA with the FlatRedBall engine. I'm probably going to rewrite it with Unity when I continue development. I can give you a download link to my current version. You'll need .NET Framework v4 and XNA Redistributable 4 in order to run it though.
I actually did compress the files, but for some reason Google Drive uncompresses it when I uploaded it. I'm pretty sure you can download the compressed folder by clicking on the "Open in Drive" button, and then on the left side you should see the "Release" folder.
