SPY FROG

On foot: arrows or A/D to move; W, ↑ or Space to jump. Tap for a small hop or hold to jump higher. Xbox: left stick or D-pad to move, A to jump. Frog Jump is unchanged: collect it in the forest and keep it for the rest of the campaign. Stomp cats from above. Side hits and falls cost a life and return you to a checkpoint.

Underwater: swim in all four directions with arrows / WASD, the left stick / D-pad, or the four touch buttons. Space or Xbox A also swims upwards. Bubble streams lift you and currents gently push you. Descend onto diver cats to knock them out, or swim around them. There is no oxygen timer.

Helicopter: it flies forward automatically. Steer up/down to dodge, left to slow down and right to speed up. Checkpoints and flight beacons save progress silently.

Final boss: the ! warns of an attack. A shadow marks the jump target; an arrow warns of a charge. Dodge, then use the recovery window to land on his head. Three stomps win, but he gets faster after each hit. There is no tongue attack.

Lives & saves: easy gives infinite lives; medium gives five per stage; hard gives three per stage. A new stage refills your lives. Running out restarts the current stage, not the campaign. Close and reopen this same HTML file in the same browser to continue from your checkpoint. Remaining lives, Frog Jump and defeated cats are saved. Private browsing or blocked browser storage may prevent saving. New game replaces the saved mission only when you press Start new mission.

USB Xbox controller: open this downloaded file in Edge or Chrome, connect the controller with a USB data cable, click inside the game and press A. Menu pauses/resumes; A starts/continues. Use D-pad left/right to choose difficulty on the starting page, and Y for New game. Unplugging the controller or switching windows pauses play. Use the Sound button or M to mute.
