This is a really great game - simple, and visually pleasing without being graphically complex. Well done!
Once you get to higher levels, it may seem like the game is constantly splattering you with paint - never fear! The developer included a setting to hide the lowest level meteors. Take note - this value is from the "base" that you have set from prestige - not the meteors' actual level. I find a value of 4-5 is perfect for absolute hypnotism. It's like watching galaxies collide!
Another note - this game is highly iterative from lvl ~50 onwards to the lvl cap of 99. But this is typical of "progress" games. Especially ones not designed to bleed you for microtransactions. It's almost a shame that it ended, though, as I liked watching the balls fly and orbit around each other.
That's about all the negative things I can say, though. I only wish it was a 400 hr game and not a 4 hr one.
