I played this game 3 times, first 2 I got a quick game over and then on my third round I got the hang of it. Moving left and right in a spot until the black hole position changes is a safe way to have an infinite round and avoid game over. I played this on solo and in browser version.
The flaws I found include the fact that the game looks a bit laggy so I'd improve the fluidity of it. It also felt weird once I got to the borders of the universe . A leaderboard would also push players into getting high scores but I couldn't find any (maybe it was just me missing it).
