Toby the Trapper

Toby the Trapper is a roguelike in which you can only harm enemies with traps you lay. Control the fast-moving Toby to outwit the smelly ogres and the unique bosses, before taking on the evil might of Wuggy the Warlock. It was made for the Seven Day Roguelike Challenge 2010, but has received some updates since. Source: The Game Website.
