This is cool! Reminds me of Geometry Wars. I both love and hate the idea of making your ship bigger with each power-up. Means that you eventually reach a point where you can't reliably avoid damage, but you can also tank hits and spam bombs. I feel like there could be at least a couple more waves before you reach endless mode, but it's a delicate balance with this game's systems. Nice work!
