My 8 year old and I are new on Tynker and he's been doing well so far. However, we cannot figure out why he can't make it through the cog gauntlet exercise. He had the code correct (we looked at the solution, which was the same) but as soon as we start the game and hit the right arrow key (go 10 steps 90 degrees), it "hits" a cog....which it shouldn't, as it's not even near one. We've tried changing the code and starting over, but it does not work. We are stuck and getting super frustrated. Please help!
