Great game
I got to Level 19... where 3 mages put Larry's intestines through a blender. I handled the first 3 with slingshots, then got munched by the other 3. I don't know if more are coming.
And that's the frustrating part - no continues. It'd be great to have the option of continuing the game. Just disable the 'submit a score" ability on a continued game. Because now while I really want to beat level 19, I don't want to go through half an hour of gnomes to get there.
Tip for people having difficulty on the earlier levels:
1) GET A GOOD WEAPON -- Make sure you kill the level 3 "boss" and take his weapon that has ice effect. Timing on that level is tight - use slingshots if necessary. The strength of his weapon varies - I've had 8, 9, or 10. Even if it's 8, it's better than your original sword. I personally like this weapon a lot - I wouldn't switch it for a 25 strength sword with no special effects.
On around level 8, there would be one big, slow dude with a ~11 strength knife with poison effect. You can use that to switch things up. Get it if you missed the ice weapon.
On around level 12, there would be one big, slow dude with a ~25 strength sword that has fire ability. GET THAT ONE. That is a slow sword with no combos but it has long range and a very good knock-back effect. Kills a miner in 3 hits! That weapon lasts me till level 19. And unless a lightsaber (available in the story mode, 30 strength combo sword) shows up, I won't turn this one in.
Also, those 3 dudes with good dudes ALWAYS come from the left.
2) USE SLINGSHOTS -- Slingshots are very good at killing things that your melee weapon are hard to reach, especially those fast running things on the floor that knocks you over. Works on mages as well. Could also use spam slingshot to quickly kill a big gnome if you want his weapon. But other than that, use slingshots frugally!
3) JUMP ATTACK -- Larry's jump attack (hit attack immediately after hitting jump) is quite powerful and knocks eneimes back. Great for stopping big gnomes when they're in mid-stride trying to hit you.
That's it! I hope that would make things easier for you.
