I'm currently doing a complete rewrite in my spare time as the original game was severely limited in scope and had lots of corners cut in order to complete it in time for my capstone project. As of currently, the rewrite has vastly better performance, takes advantage of multi-threading, and just this afternoon got engine support for keybinding in a way that I'm satisfied with. It still doesn't have feature parity with the currently uploaded game yet which is why I haven't uploaded the rewritten version.
