ya... heres something you can do to get money.... play through a level like number 3-2 or one of those... the one with the fan-boat "the swamp or one with alot of gems"... i did the one right after the uroboros monster fight... the one w/ the gem in the safe... just go get all the items/gems you want then exit the level but make sure you save it... then go to continue or level select you still have the items you just collected in your inventory so you can do that like 50 times and sell the gems or guns.... now you have enough money to level up a couple wepons..

second a little tip that helped me beat the game... in the same swamp level find the sunken ship in the NE corner and get the rocket launcher, every boss fight just equip that bad motherfuka and one shot one kill on bosses..... on the last boss just wait till he does that weird hand in the air tentacle thing and run behind him and shoot him in the eye.....
