I didn’t really plan on spending a whole bunch of time on this so the short answer is no. I wasn’t planning on implementing features beyond movement and basic actions. But as mentioned above, I am willing to share the files and perhaps work in collaboration with other developers to implement the features in their entirety. As you mentioned, I can see this as being really cool for fan base or even as a reference for Metroidvania Projects.
I’ll upload the files probably tonight or tomorrow with a bit of documentation or video to explain it.
Ultimately, I’d love for this to end up having the full features of Super Metroid and to see what the community would create with that.
Most features would be easy to implement. The one feature that I am concerned with is the scan mechanic. I’m not too sure how that would be handled in the Material editor or how else.
