Thank you so much for your kind words and great feedback! <3
It's very hard to calibrate the difficulty of the first levels without looking at people play the game for the first time, since when I make them I'm already very used to the controls, and know what I'm supposed to do... I'll keep that in mind for future games: either make the start very easy, or get human feedback on it.
I don't know what kind of bombs you are referring to, all of them have feedback and particles. Though the bomber might be a bit misleading because the bombs explode when the red circle disappears, which you might pay less attention to since there are many things going on.
I'm glad you enjoyed it!
