Actual game here: https://scratch.mit.edu/projects/154866875/ Go play it! It's worth it! That's not a lie. Go play it.
I just made it so you have infinite arrows and shurikens. For those who haven't played the original, arrow keys to move, up to jump, space to attack, and z to change weapon. This is the hacked version, so here are the changes made by the creator: Katana makes you fly - You can grapple onto the edge of the stage - 5 arrow insta-shot - Enemy shurikens bounce off of you - Break targets with katana - Swim in polluted water/poison - Piranha fish are scared of you
