Rings (TinyBookshelf)

Rings is a timing-based puzzle game.
... maybe a little luck-based, too.
Try to clear each level by hitting the target before you run out of shots. But beware: There are barriers in your way, and they can be tricky.
What's your high score? Can you clear all ten levels?

Enjoy!
Known bug: Sometimes the GAME OVER text pops up prematurely? Haven't figured it out yet, will update if I do. You can keep playing 'underneath' it or hit X to restart, so it's not game-breaking anyway.
