First of all thanks for playing, and I'm glad the controls were fun. I was really trying to make sure they were annoying but not too annoying.
With regards to the bugs: Yeah... I fought with the car disappearing for at least 4 hours during the jam but every fix I tried just causes worse bugs. Yeah there's a pretty decent chance none of the stores sell to you because I accidentally made an "or" an "and" instead. I also agree that the stores should pop out more, and the map was definitely too simple.
Thanks again for playing and I appreciate the feedback!
