This uses only the mouse. You left click to fire and move the mouse to move. Hitting the projectiles given off from the boss will make you lose health. This is only a demo I plan to do many more projects and levels with this. Also this has awesome music with it so you should turn up the volume. If there are any glitches or bugs please let me know.
I made my project based on Matt Rosak's game Bullet Heaven that is on Kongregate. I do not own and did not make the sprites in the game all credit goes to Matt Rosak aka Kupo707. HalcyonicFalconX aka Phyrnna gets all the credit for the music that was from the original game. And other people I may have forgotten to mention get much of the credit.
