I want a game called CatLands A simple 2D game made for my website i need it in net beans so i can upload to my website. I want pixely graphics but JFrame resolution of height 600 width 800 by default and re-sizable. I need the player to spawn as a ginger cat named Noodles in a arena where you kill dogs, earn exp move arenas and every arena past the 100th arena is computer generated. I want the players attacks to be based on classes which can be earned by collecting exp. The classes start with with normal that you get by default then ninja cat which cost is 100 exp archer which is worth 200 exp then assassin worth 500 exp then nyan worth 1000 finally nyan god that can be used once every arena times for 5 seconds that shoots plasma lasers that go through everything. The classes can be changed at any time using a hot bar on the bottom of the game. Email me for more specific info.
