Thank you so much for playing our little game and your feedback!
The balancing is something that sure needs more love; the maximum enemy limit was something we planned to add and then forgot to realize in the heat of wrapping it up and submitting. Excellent suggestion with the color cycling idea, I think @Liioni is going to look into that after the jam is over, cause that is definitely an intuitive way to cycle through!
Thanks again and have fun with all the other games of this cool jam!
