in terms of the bits i needed to record guitar wise, there's only really 3 parts, the main chorus section, the verse/weird rhythmic bit and the breakdown. I reused these riffs/ melodies to make different sections rather than just repeating them, and the drums are the only big difference between sections that feel similar (e.g the part at 1:04 and the bit at 2:00). Then i just made some synth layers to fatten it up, and a lead melody to go over the choruses. When you lay it out task by task, it isn't too bad, and then i have a solid base to add all of the extra little flourishes like the impacts, screams, and other sound design elements. Basically the way i work under a time constraint is finding ways to reuse elements while keeping it somewhat dynamic and interesting. Hope this helps, and i'm glad you liked it!
