Your polish is always top notch. I'm really going to have to go back to all your entries after GDKO and study your particle effects. Those were fantastic.
Endmark introduced me to the term "juiceonomics: bigger number = more better!" The scoring felt true to the original. But adding 00 to everything really makes the player feel more epic. Passing on that suggestion.
Overall, fantastic update to the original. You really nailed it. Great work!
(And if you don't mind my asking, how did you handle the color changing for each wave?)
