could i tell if this is open source?

I wanted to ask if this spiderman is open source, it is from sludge and I read that it was open source but Acey relaunched it in 2011 or there and I don't know if it is still open source, please resolve this question for me

I talk about this spiderman (sludge)

could you help me with this question

If you use it give credit that's all I can think

If it is open source it will give you equal credit

Not to me to acey and and sluge

that's why acey and sludge gave me to misunderstand haha

Well, the real problem for me is that I tried to contact acey but he still hasn't answered me

sludge said this at launch
"This character is completely open source. Take whatever code or sprites you want, at least mention me (Sludge) in your credits. I see a lot of WIP pics for characters like: spider slaughter, scarlet spider and symbiote spiderman, but they seem to just disappear (¿ cancel?), so if you are doing one of those characters, feel free to use this spiderman as a template for your spiderman. If you add new attacks, study how I did the AI ​​in cmd file and in attack states, send me an email if you need help "
