It's obviously just the 137th clone of JLP Kangaroo, same skeleton, same architecture, same issues. If you want a "proper" solution don't expect it to land freely on GitHub. Knowledge and experience comes with a price tag. I could brag that I managed to write from scratch a completely working Kangaroo that currently works 6x (six times) faster than both the original and all the n00b clones out there. I'm not gonna sell it or release it because for one, I don't need to prove anything to anyone except myself, and secondly, it's really ok if no one believes me that I can squeeze out 900 million jumps/s on an underclocked RTX 3050 laptop GPU that can never reach more than 200 Mops/s with JLP's app. BTW, the stats on JLP's program are biased, the real speed is slower than the one printed on the screen (there's some non-sense smoothing speed computation in there, and the computed time durations are bugged between worker threads and main thread). Real speed is 10% slower due to these bugs. Whatever.
