Thank you very much! Makes me really happy to know you like them (specially since I did them in the last few hours left before deadline :) )
About the traffic light boxes... totally.... my bad. I left the basic unity cube, didn't even change the material :(
Is that kind of things that you made to test a script, and once it works, you forgot about it completely. :)
Glad you like my other games :D
BTW, you did a great job on your game too!
