Thanks for playing, I'm glad you enjimmed it!
You're not wrong, there weren't any sound effects. We had an issue where Git corrupted our project the day before the deadline so we had to revert to a previous version of the game which ended up with us losing over a days worth of work. That's also why the music didn't loop. We didn't realise these issues until after the deadline so unfortunately we weren't able to fix them in time. We plan on continuing working on this game, and fixing the various sound issues is going to be in the first update we do after the Jim is over. :D
