Great use of tiny swords! Some feedback. If you ever wish to expand on this I would have speed boost powerups, and new goblins. Additionally, maybe more companions to help build.
Thanks. Since this is a game for JAM, I went for the simplest solution that can be played quickly and is not complicated or too difficult. I don't know if I will develop the game further, but if I do, I have some ideas based on your suggestions.
