The consensus I'm getting from these comments here is that the game is addictive, which I for sure have noticed too while play testing! Your two points are very true, I really wanted to get the audio in, but there was just no time left sadly, this whole project was made in every spare minute I could find while travelling with some friends. And of cause, the balancing; I think most of the values are fine for a jam entry but I agree it's way too easy to reach the quota, it only really gets challenging and then very quickly impossible at around level 39 or so.
Thank you so much for playing!!
