Solid game! The story and theme were well done! I quick explanation of the score and the cost of the defenses would be nice. Also it seemed like some fireballs went further than others.
A phoenix is a great fit for the theme! Love the music and atmosphere. The fireball sfx seems at odds with the rest of the audio. I love the idea of being able to upgrade the phoenix. Well done!
Cool idea to get procedural generation working! My camera was slowly spinning when I focused the window with the mouse. I hope you continue working on this!
The car NPCs are hilarious to watch! They were making my friends for me. At first I didn't realize I needed to die, but once I did it was even more fun.
