Use WASD to move, and use your mouse to click buttons. When attacking, press space to activate it. The red bar will start flying. Then time space at the right time to attack the knight. Otherwise it'll be a miss. For most of the moves, dodge the attack. Touching the attack will cause you to lose HP. When the dark knight uses Super Scythe, if it's green, move, or you'll get hurt. If it's blue, don't move or you'll hurt. There are two items: the HP potion and the ATK potion. The HP potion restores 75 HP, and the ATK potion increases your ATK stat for 2 turns. When using defend, your defense will increase by 3 for one turn. It also fills up a part of the power meter. When your power meter is full, press unleash to launch a giant blast at him!
I made all the sprites except for the dark knight (I got it from clipart) UPDATES: HP potion adds 75 HP instead of 50. Added new attack: Super Scythe. Added new power meter and defend increases DEF for one turn.
