Not sure why anyone's downvoting you, but I suspect the name is 100% on purpose - it would be quite the coincidence otherwise. I remember a game called Speedball in the 90s, which was very successful - this is nothing new!
Ofc it is on purpose. This guy goes by name Frank Lucas.
Frank Lucas IS a great mind and developer. To make a connection between two people that share the same name and imply similarities on the sole basis of that similarity, doesn't make sense.
Frank Lucas was a notorious USA based heroin dealer/trafficker who died this year.
Comparing the words angeldust and the very common word "speed" is not comparable at all. Also the game looks like it's targeted at smaller kids. It would be like creating a minecraft clone and calling it "meth-heads". Thats 100% not what he is doing and if it is, then it's pretty insane.
I haven't heard the term angeldust before, FWIW.
Not "speed", "speedBALL". It's another example of narcotic slang - I think a combination of heroin and cocaine. Again, it's quite likely whoever picked the name was aware of the meaning.
