Thank you everyone for your support so far. I have used the money to hire a producer for making a custom song for the upcoming Assault game mode. You can already listen in:

For the music style, we tried for a fast complex electronic sound, or complextro for short, while the overall layout is more like psychedelic trance where things fade in and out all the time. And to give the entire thing a sense of progress, as you blast through waves of colorful geometric shapes, we went with a formulaic big-room layout with peaceful breaks and multiple hard-hitting drops. But of course, given that this is video game music, we had to make the intro and outro short and succinct. Plus it's quite fast in general, as this mode will hopefully be even more chaotic than the first one.
