Thank you! I am really glad you enjoyed the game, esp. music and sfx, and yes this was intentional and somehow related to the theme (the guitar was playing B9 chord repeatedly, and the jump and bump sounds are high and low B notes).
I am afraid that the very brief description of the game, although intended to increase the surprise factor of the game, might have just backfired, and also the lack of polish could have lowered the expectations of the game.
Thanks again for the feedback, it really meant a lot to me :)
