Hey, I think that your video may well be my first YouTube gameplay video! Thank you for that! I’m glad that you enjoyed it. ^___^
I don’t think that I’ve played Silver, but having taken a quick look at a Let’s Play I think that I see what you mean. A closer comparison (and not by coincidence) would be Die by the Sword, which used a very similar mechanic.
In all fairness, the version posted here is quite old now. Indeed, I ended up shelving this mechanic in favour of a simpler, less-physical approach: while I do think that this approach could work, getting it quite right would seem to involve a rather more rigorous approach to the physics, which I’ve decided to back off from.
The new version has some distinct similarities, but I think that it’s a bit more intuitive, if less nuanced.
