Ok so here’s a somewhat professional review (Not 100% but about 55)
The chord progression at the beginning is nice but gets very repetitive. I do really like the bass pattern. But it’s ends to quickly. The vocals are good. Both drops have interesting sound design. But the best pattern makes it not at all Brostep like. It’s more like riddim. You know how I feel about riddim too. Try to keep in mind that Brostep drum pattern has some breaks in it and not a long repetitive drum pattern.
In short, make it less repetitive, the second game art seems like a copy paste of the first. But you got the right idea, and I see a lot of potential in you.
