I think I sent you a message through the feedback form. I wish there was either Lua 5.1 scripting or a clean C or C++ base to go off of. Customization, lightness and engine agnosticism are my main points. I'd also wish you just released it instead of having a website for months that says coming soon. I understand it's a free project but anything I did I released right away to pique interest and get comments on.
Feel free to email me in the email I included.
