Thanks a lot !
We're really glad that you enjoyed the game, although I can see how it can become repetitive - we will add a bit more diversity if we ever decide to expand the game, but we kept it simple for the jam.
For the music, we tried to keep it a bit discreet so the volume isn't very high and we forgot to make it loop so maybe that's why you didn't notice it ? Another comment did say they heard the music so it doesn't seem to be a problem with the export.
