well the controls are arrow keys move and space shoots, you kill the spiders and eventually a big one will come and you;;have to kill it. there quite a few problems, the first being i took a few hits figuring out the controls. and when i did the shot will sometimes not shoot the way m facing, Ive had it go behind me and below me which results in me taking hits. also the big spider is near impossible to dodge because the walking animation will glitch in two ways. the first being that i will slide (which almost guarantees my next shot will go behind me) the second is i will suddenly stop moving all together, since the boss spider can drain your life without actually touching you this is a major problem. also after killing that big spider the game ends, there's no replay button or anything just a screen with text that roughly means i won.
Sorry mate,the controls are unlisted,its in spanish and well...it doesnt have any goals
