Hi! How close can you get to using a specific mechanic like R-Type's "force" or Zero Gunner 2's control without committing copyright infringement? Or IPs "only" apply to audio and graphics here?
I love the first one and wonder why there aren't more games like that series gameplay-wise... And also would like to introduce a ship/mode in a future project with Zero Gunner 2's control scheme (I've never seen it outside of that game)
Thanks!

The better question to ask now is if it got copyrighted or not. In most cases certainly the mechanics never got copyrighted. But there is a modern example of that...
