Very nice bullet hell space shooter
You've done a great job of putting together an interesting and challenging game. The difficulty curve in the final tier of levels is extreme! It was a little painful grinding for money, but once you found the "cash cow" levels things started shaping up. High level shields and attractors were still out of reach by the end of my game, but maybe I'll come back and grind it out a little more later on.
No medals? That's a shame, because this could really have some nice ones. There is some slow-down between the on-screen enemies and shots, but in a game like that it actually helps a bit. If I had to choose one thing that I found particularly disappointing, it would be that expending cash for Smart Bombs doesn't rid the screen of enemy shots. Of course that just increases the challenge level even more--especially when you're getting mobbed by thousands of enemies all shooting their own unique patterns of bullets.
Graphics aren't amazing or anything, but who cares? This is a game of dexterity and skill. Besides, more complex graphics would exponentially increase the slow-down. The music is awesome, but even these great tracks get too repetitive after a while. Props for including music and sound effect mute buttons! Always a wise move.
