So i have added a cutscene with little bit of story like why the character is killing those enemies and why we are so aggressive and why we finding and killing every one of them.

I added 3 more levels and all those levels are quite big enough to not make u bored and u just wanna beat the game and also added a level selection screen so if u died or something u can just go on to level select screen to pick the level u wanna try!
