Aye man, don't worry about it at all! No need to feel this much pressure over a tiny little collab like this one. Had fun making the projects and exploring a bit my creativity with that song, so in the end my time was not wasted at all. You shouldn't feel like you failed any of us, since there wasn't really any prize and most people joined in for the fun of it I suppose. Shouldn't be a reason to stop collaborating with other people either, in my opinion.

My brother in Christ, it is not that deep. it's just a time management issue. you're fine. My time wasn't wasted I had fun collaborating with you and would enjoy doing it again.
