I really wish I could play the game in the first run I won after placing the first tile but now I always get an error message: 
the game seems fun and the idea is very cool :(

I'm sorry to hear that. Unfortunatelly, this bug happens when you place a road on a tile right after it has been discovered or vice versa. (Please see the section "Known bug"). I will repair it right after the voting period, I have noticed it few minutes after the deadline. You can avoid it when you do not click so quickly. (I tested it on the touchpad and I won't do this mistake again. 😀)
