Trolls can't break this tower

The objective is stated plainly: break the tower while avoiding the trolls guarding it. The central scene shows a barred enclosure with a troll behind the vertical metal bars, set inside a bright blue, block-built room.

A large green button sits on a dark base in the foreground. Beside the enclosure, a numbered keypad displays digits 1 through 9, along with green check and red X controls, while “1+2+3+4” appears above it. The visual style uses simple geometric forms, saturated blue surfaces, and bold interactive-looking panels.
