I don't know, but everything works for me. I put 5 level 1 mines and then a level 1 station. Maybe you accidentally built a level 2 station (a huge pipe).
Sorry for such difficulties in the game. I'm basically a programmer and I couldn't explain what to do in the game and balance it. Our game designer was busy and could not participate in the development ((
I tried again and it worked this time, I guess I must've been doing something wrong the first time (probably accidentally clicked the lvl 2 station). Really fun game! I made through it seven waves :)
to be honest, i am cant survive before 6-7 wave)) this is good that you liked our game. thank you very match!
