Took me a while to get how the game worked as well but I enjoyed it! I feel like this game really fits the scaling theme in the sense that I felt powerful as the game went on, like you're scaling in power or something like that lol. I agree that working on this further is worthwhile -- leaning into that "super fast meteor zooming through space" power fantasy with more effects and maybe having the camera zoom in/out or use funky effects would help improve on the already great atmosphere this game has.

I really enjoyed the slingshot mechanic as well. The way you implemented the steering controls was pretty awesome, and I found myself replaying the game over and over and over so I could get a better grasp on the controls. I agree with what mjholdham said! Really great job on this game!

Once I figured out how to enjoy the game I quite liked it! Obviously the audio is sparse, but the UI and overall presentation is nice and clean. The feeling of inertia and speed is good, but more feedback would make more sense of the gameplay e.g. a line between the meteor and the cursor would convey the idea you're pulling it around, and maybe make it clear that pulling left/right doesn't have an effect (as far as I can tell). The trail that triggers as you build speed feels like good encouragement to go faster!

For me the game really clicks when you're ducking and weaving between planets and avoiding the walls, and the slingshot mechanic was a nice simple way of making the player dance on the edge of danger. It felt good just to sway the meteor up and down while avoiding the walls, reminded me of slithering like a snake! If you're going to work on this more (which I think would be worthwhile) you could add some kind of speed boost when you're swinging the meteor around.

Overall, with a bit more polish this would feel like one of those classic Miniclip games from back in the day!
