Wow what a trip, I made it to dawn!
I love how ridiculously big the soul prices get, and the enemies look like they're burning diesel when they come for you XD Really great sounds and effects!
I made it to about wave 52 before the enemies started closing in on me and doing some serious damage, but then... the prices started acting weird and jumping around, sometimes they were negative and paying ME when I upgraded. I mean, yes please! But I definitely took advantage of that and maxed out several stats. It's so satisfying though when it's like a constant barrage straight into the face of that little hooded guy. Great job!
