Oh, DAMMIT. I thought you had to unlock the upgraded projectiles like you do in the non-player-made version, and then you could come back later with better stuff for the golds. I was plugging away at the Double Glazing castle with the single wood log. Took me 60 shots.
This is an awesome game, but I just can't figure out the last level (48) - I always either get 1g too many after placing my last piece, or get the wrong number/spacing of gaps to remove the line I need (it also doesn't help that it's 2am now, and my brain hurts from 2 hours of the same puzzle). Still, one of my favourite online puzzle games, and I hope you make more!
