As Fuzzy said this is a great submission. I think you should not be disqualified. the sounds feel like they could be from an actual nokia 3310 to me. I am trying to say you captured the vibe of the phone and that is more important than being totally accurate with the limitations.

Thanks, it's a great feeling seeing such praise for something I made myself!
Also all of the sounds were from Nokia compatible sound fonts, but I couldn't figure out how to do the single channel audio with the one day I had for this jam. If they do disqualify me though, it's completely fair, I just really adore 1-bit art and wanted to participate!
