nice effort
well i can see huge potential here and u can tell a great deal of effort went into this so u deserve good marks.
several bugs i found were that his speech text was on top of the tutorial text and it wasnt possible to read either at times. and also i ran outa bullits at one point and tried to change to knife but didnt know how =/ then i mashed my keyboard and i got my knife back but i lost the gun lol and i dont think i coudl get it back :(.
oh and also the enemy health bars were in red and the backround was also in red so it was too hard to see that also
a few more tweaks here and maybe a lil more polish and it would be front page material.
fix text, fix health bars.. lil more polish to it make it lookbetter,, add in weapon swap, -1- knife -2- hand gun -3- machine gun- etc etc
good job tho hope to see another :) oh.. and add medals :D
