This is a really cool game: beautiful graphics, tonnes of bullets.. .and I really like the 3-second countdown after a pause. That helps a lot when getting back into "dodging" mode! Five stars from me, for sure.
Oh neat! It looks like in the undead levels, when those bone walls spawn, you can leave one up after the last enemy has fallen and just wait for all your arcane charges to generate before going to the next wave.
One neat little trick I just tried for the Survival levels: use rage injection on the bosses and get out of the way. :) (Not good if you're trying to rack up kills, but great if you're trying to survive for a certain length of time).
awesome find. im so -itching to nerf it hahaha.
