Boomerang — free browser game

You start with three lives and a single boomerang in hand. Use the mouse to aim into the upper half of the screen; a dashed line from the cyan player at the bottom shows your aim direction. Click and hold to charge a yellow power bar at the bottom — a short hold gives a small tight loop, a long hold a wide one. Releasing the button throws the boomerang in your chosen direction; with a constant spin it always curves to the left, making a full loop before returning near the player. While in flight, the boomerang pops any balloon it touches: red +10, blue +20, gold +50. Hitting multiple balloons on one throw multiplies your catch bonus. As the boomerang comes back, a green 'catch' ring appears around the player — click while the boomerang is inside that ring to catch it: +25 plus +15 for every balloon you popped, then you can throw again immediately. If you miss the ring or the boomerang flies off without being caught, you lose a life. The trick is that the angle and power decide where the center of the circular trajectory falls — a low angle slices a big balloon cluster, a high angle reaches far corners. Because the curve always twists the same way, you have to plan 'aim upper right so it comes back from upper left'. On mobile, tap-hold-release replaces click-hold-release. R or Restart resets the game; the highest score is saved automatically.
