Hi! Yes, many of the edits were done by myself and I've written many scripts (such as the particle system) for the game which is also why it took so long to get to this point :D Glad you enjoyed it & I hope you stick around for the next release!
Wow, thats crazy. Are you a programmer or are you working in the gaming industry? It looks so professional that I can't believe it's just a selftought hobby of you :D
