Thank you for playing the game! The enemies moving during the gathering phase was intentional to give the player incitement to jump back and forth between the dimensions. We have now been talking about having a little "cam" show up during the gathering phase to easily see where the enemies are and when you have to come back, I hope that would make it easier to determine when it was time to stop gathering and return to buying towers!
I am sorry about the music! We were setting it up so it would be possible to change the volume, but sadly didn't get that far! But will bring it with us for the next jam that we should definitely focus on it! Thank you!
