The message when you run out of money blocks you from placing road spikes and it's happened more than once now.. When you click where it is even if you click the road it pops back up and blocks you
I was on level 52 and I lost because the lag was so much [due to the no quality change option] that i couldn't click anything and it froze my controls.
I don't like the curvy paths.. I only like the ones with 90degree turns. The squarish maps. You should equal out curvy maps and square maps on the next one if you make another.
