When I loaded the page the embeded game viewport was huge and ran off the edges. It looks like it is 1080p, which is the size of many people's full screens, but this is embedded and will have the browser around it. I would suggest dropping the viewport size down so it will fit inside a browser window, and allowing people to go to full screen if they want the 1080p size. Worse, when I started the game, it only used about a quarter of the space and would have been fine with a much smaller viewport.
I like the concept of the game, and the story about trying to use a wormhole to move the whole Earth to save it, rather than the typical evacuation of people from Earth.
The intro is nice, and I like that you have a clear way to skip for those who want to, especially if replaying. The art is pretty good. The music fits the game's theme. The UI elements are good, though I think the spin indicator at the bottom left is a bit too big and can obscure asteroids coming from that direction. The game was not so difficult that it was an issue, but it was a bit annoying when I was trying to click on one that went behind it.
I played until the timer ran out and nothing seemed to happen. I still had asteroids showing up for a while. I then spun up to fill the bar, and after that I stopped getting any more asteroids, and the bar did not drop back down at all, but there was not indication the game had ended. It would be nice if there was a game over screen, or, ideally, ending cinematic.
During most of the game I just kept the spinning bar near the middle, pressing A/D as needed. I clicked on about half of the asteroids and let the others get smashed. I rarely used the right click to free, and found it difficult to target an asteroid to use it, as they were spinning so fast. Once I got the rhythm, the game started to feel repetitive. I debating ending sooner, but looked at the timer and figured I could wait for it to end to see the ending sequence, which made it disappointing when there was nothing. You have a decent base here, but it could use something more.
