hello again,ive just completed this game a second time. I have found new things out about this,collect as many keys as possible for all the rooms,I just cleared all of them today,you need alot of them to get to locked doors. There is a big final robot you must destroy at the end. Destroy all the boxes in the room where theres all diffrent kinds,I think all of them,and there is a medium size gun,pick that up and equip it. When you get to the final robot its alot more easier to kill for you. To get the full version of the game click anywhere to buy it or if you have one enter your e-mail address.
