I really like this! It's always nice bumping in to a well mixed, well produced track on Newgrounds lol. Too many times people are barely utilizing the DAWs or free things on the internet.
I honestly really like the whole thing, with chill step I usually assume it will be more ambient and take its time, have less major changes, etc. Everything felt very appropriate, and it never got overly repetitive which is very good for a 4 minute track like this. You just kind of groove to the subby wubs.
The only compliant I could have is that I would've like to see maybe a bit of a break that surprised me or something. A lot of artists on Newgrounds that I really like are ones that surprise me. While its all super good, its really nice when someone has the nads to push the beat that much further in a short break or something. You could say you did that with the heavy part towards the end, but I guess I was thinking something more melodic. Just a thought.
Keep making music please!
