Thanks to the music, sounds, and smooth scrolling background, I was very relaxed while playing this game. It took me a second to get the hang of the controls, but once I did, the game became quite addicting! Maybe it's a skill issue, but I would've benefited from a trajectory indicator. I definitely think this game is for people with higher skills than I though, haha. My high score was 10 :)
Also, I think the simplistic art works very well for this game. Not all games have to have detailed art to feel polished. Just keep practicing!
