Author here. That's why it's not listed on the official scheme.org website as one of the implementations. I was told that to me called Scheme, you need TCO and continutations.

I made one attempt to implement them some time ago but failed. The code was not working. I based my implementation on someone else code. And later turned out that the call/cc that I based my code pm was not even full continuations and failed my test case.

Most Toy Scheme implementations don't have TCO and call/cc so I can't use them as a reference. But I have an implementation that is really promising that implemented them, the code is very minimal and I can base my code on that.
