144. Game is very fun! Given your current leaderboard, may come back for a second playthrough and see if I can get top 10 ;) Boosts are a big deal, of course, but the exponential enemy speed growth means that past level 14ish it doesn't much matter if your speed gets another ~2% improvement-- nitros (and maybe drills, haven't used those effectively yet) are the only things keeping you alive. Also for the last several levels of a run, when you're barely making it each time, coins are where your points come from. And when you know you're dead, it's time to fetch coins till the ref calls the game on account of everyone else finishing.
Pretty happy to make it this high on the leaderboard on my first try, though D: I could probably have gotten another 1st place with better early play in terms of boost collection and mid-game nitro usage.
