I like the style and animations. How did you do the 3D model? Is that a shader, or are the models actually composed of lots of little parts? Also, sorry for all the questions, what's the font that you've used for the title? It looks really good!
There really isn't much to do, but I still got some satisfaction out of destroying the cars and buying upgrades. My final score was 52 destroyed vehicles.
Also, Godot FTW! I also had issues exporting for web, so I understand the struggle.
