I love the intense music for this game! Also- I love how many enemy types you made, and the fact that it's a solid tower defense game. I'll probably show it to my kid tomorrow, so chances are that there's gonna be another comment from me. Especially since I got defeated before the end, and I see I need to get to the end to see how the game fits the theme :)
On thing that needs more work here is the graphics. I'm not really great at graphics, so in most jams I work with someone who does graphics for me :)
Over all- needs some polish, but a solid game nonetheless!
