Thank you for playing and thank you for the feedback. Oh, yes, the game was made to be played with both a mouse and a keyboard, I have never tried it with a trackpad, I'm not even sure it's possible to make a good control skin that works with a trackpad. Also, The idea of the yellow and white bullets is that you have to combine them to optimize the damage and also that you can keep shooting while charging because I don't like to stop shooting to charge. However, some people find the white bullet not that useful, so I guess I have to tweak it. Oh, and the browser versions looks weird and you see white things poping up and down, Idk how to fix it.
