Absolutely loved the art style! Even with the tutorial, I did have trouble understanding exactly how the summoning queue worked at first but I figured it out by the end and was having a lot of fun with the escalating levels of carnage. This may not be an issue for the downloadable builds but the web build seemed to have, what I'm guessing, is shader compilation lag since it would freeze momentarily when new enemies/effects spawned for the first time. Regardless, really great game!
