Thank you for playing the game.
On the note of the duck sounds, all of them were actually voice acted specifically for the game, so we did hope they would leave a good impression. On the note of keeping track of progress, the group has talked about it and we did decide that, if we had a bit more time, we would add a way of telling which wave your currently on. It didnt come up in testing as we could see it in the debug menu and we forgot that wouldnt be visible in the finished game. Thank you for your feedback
