It wasn't clear to me at first that I might even need to fight, maybe the starting area could have something to kill as well and some signs to the "Goblins treasure" or something like that, to direct the user to take action. It might have also been the case only for me since I found an exploit and didn't need to really kill anyone :P.
If you keep spamming the "E" button you will keep collecting that item until you have had enough for the bridge. Bread worked the best for this.
Overall it was a enjoyable game, the "combo" on attack spamming was a nice addition - could have more of these combination moves in the future to make the gameplay more "advanced".
Good job!
