Just make a gun with Max Damage, Energy 20 and Max Rate, and put some upgrades on Energy Regen, and everything else on Damage/Armor/Armor Regen, and you just got your way to the end of the game.
That was quite easy. At the start, just use Sleeper Block and Sticky. When you get the Piercing, it's easy to finish the game. Start by making a Stinck at the far west of the map and a Piercing at the far east. Then, build another Piercing above the first one and you're pretty much done, but you can sell the Stinky and build 2 Piercing to make them suffer. With those ghosts, just build the Eye one above those 2 Piercing. After you get booster, fun will start. Put 1 of them above Eye, unless there's no ghost on this map, so you put 2. When you get magma, putz this order, from under to above: Booster, Piercing², Booster², on both sides, and put Magma/Stinky/Cursed on the ground, and you're done for the rest of the game. First upgrade Sword M Dmg, then go for the Stun, or the +1 block dmg, it’s pretty much your choice. Meteor is just for fun, and the Deadly Teddy one is useless, since you won’t let them reach your toys at all.

Start by making a St at the far west of the map and a Pier at the far east. Then, build another Pier above the first one and you're pretty much done, but you can sell the St and build 2 Pierc to make them suffer. With those ghosts, just build the Eye one above those 2 Pierc. After you get booster, fun will start. Put 1 of them above Eye, unless there's no ghost on this map, so you put 2. When you get magma, putz this order, from under to above: Boo, Pierc², Boo², on both sides, and put Magma/St/Cursed on the ground, and you're done for the rest of the game.
Be a Stark One, Agile. Max Slash and Speed/Precision. Then, max Coordination and Passion. You can also put some points on Focus. After, you can max Stamina/Bodybuild or Bodybuild/Strenght, it's really up to you, although I prefer the first one. And max Focus, followed by Fortitude. You can also put some points on Fortitude while maximizing Focus, just to get decent HP. Also, some Armour helps if you got a good piece of protection there. Only use Excellent/Perfect armours. About weapons, get those two small slash swords for start, and after them, get the big 1h slash sword, two of them make some damage. Skills, get the Potency and Ironwill to the max, they're your priority. With the last buff of Potency, you can make up to 600 damage, which kills every single enemy on the game. And Innerfoce boosts both your damage and HP. After all this, go for the passive skills. And money isn't really a problem, I finished the game with almost 24k.
