Fun! I liked it! Catching ghosts isn't that easy, since you have to line up with the trap and the ghost and wait for the capture to line up with it. But that didn't put me off the game, and I think other players will enjoy it too. I think a little simpler wouldn't hurt. For example, the ghost's pull won't be interrupted by a projectile hitting the player.
The AI must have created the background, but still, good job getting it. Cool sound.
The leaderboard must be fake.
Bugs: 1) The final screen doesn't block input.
2) Closed traps don't disappear.
3) Two traps closed at once.
