It's fine… but starts being repetitive pretty quickly. I could keep going for a long time, but soon enough it starts getting boring. No new elements get introduced and it doesn't get progressively harder.
Because you can only skip between platforms in one direction and the skipping is fairly slow, you also can't reliably collect every gem which appears on the screen even if you try.
Additionally, the score count is too small and harder to read, and the YouTube link in the menu points to the wrong game. But you'd frankly leave a better impression by uploading *that* game here.
