TRAPCHAIN -Prototype-

Set the traps. Watch your target walk into them. Chain the chaos.

TRAPCHAIN is a physics puzzle where banana peels, pushers and fans turn one bad day at the office into a perfect chain reaction.
Your boss always does the same four things. Read his routine, set your traps, press Run — and watch him slip, fly and crash his way to a knockout.

Features

• Read the routine: the boss's path and actions ① to ④ are shown before you place anything.
• Chain it: traps knock him into furniture, furniture knocks into more furniture. Every hit in a row raises the combo multiplier.
• See why it worked: the result screen breaks down every hit and every point.
• English / Japanese, switchable at any time.
