I can't beat Hornet.

Is it worth continuing if I've been stuck on Hornet (1st one) for around 3 weeks?

I'm no closer to winning, think I've got to the 1st pause/rest bit once or twice, despite having read guides etc.

If the answer is no, any suggestions for other games I might enjoy? *Got to HK via Zelda and have really enjoyed it, just can't do it!!!
