Hey as mentioned in other comments as well as in the submission and in the in game credits we can't take credit for that. The world and all the models are part of a Synty asset, the only thing we can take credit for is styling it that way via a custom shader.
We did make the music and yeah totally agree, should have come up with a few more tracks or something to even things out a bit, but the game itself is pretty short. Good news is you can just turn off the music from the menu and listen to whatever you feel like, I suggest Hotline Miami soundtrack lol.
Thanks for playing and I'll check your game out if I'm able.
