This is ridiculously good. I got a great ring combination on my second run, with a couple of big explosion rings, the corrosion ring, and the ice shard ring that sends three projectiles, and defeated the dragon with two attacks - my next run I got completely destroyed by the dragon after accidentally hitting myself with a projectile that froze me D;
but yeah, absolutely loved it. the art, the gameplay, the spell effects, everything. the recoil letting you zip across the map at mach 10 was great too. I can totally see a full version of this being a hit :V
