Ooh... boy. There's a lot to note about this one.
As everyone may have added, this could have used more time for polish. Seemed to be an embedding error at the first part, I didn't even realize I was moving until I saw projectiles coming after me, and there's not much challenge.
While that goal of 1000 stardust is nice and all, I was expecting faster missiles, more obstacles than the cars, or even a way to de-buff the player. But this was quite underwhelming, leaving no challenge for the player. Yes, there are multiple obstacles, technically. But I was expecting more of a way to punish the player, rather than making the player way too fast to be able to out run it entirely.
There are also quite a lot of bugs, such as the game not ending properly, or having the enemies just drift off into space without de-spawning, or not being able to see my health bar.
Unfortunately, I'm going to rate this pretty low, a 1.5/10. The idea you have is great, and I see where you're going with it, but I think there can be more done. Please don't be discouraged by this comment! While I might be a random stranger who makes games, I actively encourage you to keep making more games to keep understanding the "game schematics" and whatnot.
Good job!
