Use "WASD" or arrow keys to move.
Space to hold or drop your heart.
"J" to attack while heart is on the ground.
Don't let the enemy robots get your heart.
Don't let laser touch your heart, kill the robots to keep the laser back.
You have to hold your heart every so often to rebuild your bleed out timer (timer at the top), when your not holding your heart it bleeds out. But be careful because you cant attack while holding your heart!
Survive as long as you can!
I don't recommend the HTML5 version I was just testing it and it runs really slow. Not sure how to delete it.
