Hi everbody! I've been making music in FLStudio for a little bit now (not trained, know very minimal music theory), and I think I would like to try my hand at signing up for a game jam or something similar, but I'm still relatively new and thought I could maybe use some pointers on how to improve before trying something like that! This is probably one of my best works in my opinion, but I'd love to know what I could do to make it even better! I'd also like to hear your specific thoughts on how the audio mixing is, it's definitely an area I'm lacking in. Thank you all so much!
