Nice visuals! I really liked the way the subatomic particles planets rendered, like they came into existence from nowhere and rapidly grew vegetation on their surface (even though it was just objects entering the camera's clipping distance).
Gameplay was pretty good, though it did feel like it was hard to control the ship precisely. I'd often be a little bit to the side of a hole, then tap the key and end up on the other side of the hole.
There could have been an in-game explanation as to why the player should enter the holes, I had to read the description for it.
Bug: The "Try Again" text/button stayed on top of the "Menu" button when I pressed Esc after death.
