As of this morning my progress has been reset for unknown reaons. The Save-game is just, gone. I have not cleared my browser history or deleted/reset anything else recently.
For those struggling to get that 100x end combo achievement: Set pattern to straight, keep your mouse still and hunt those yellow thingies (whichever you chose) and avoid red. This is really doable. Once you hit the 100x Combo mark, move your mouse offscreen so your game-cursor disapears.
Happy hunting!
