Personally, I like the challenge the game poses better with minimum upgrades which is why I didn't prolong the game any longer or have an end screen, haha. Glad you liked that mechanic though, blowing up cars and the combo meter is something I quickly added in the last hour during the extension to try any make the game fit the theme better, it almost didn't make it in because of a bug I was having with it and I didn't get to test it so I was worried it might be unbalanced. Maybe it kinda is, but fun is the most important thing to me. If I had more time I would have given the cars an animation for being destroyed so it feels cooler.
