Use the mouse or your finger (on mobile) to move your character. Dodge the enemies and their bullets. (The player clones don't hurt you.) At the very beginning, there will be hardly any enemies. It will get progressively harder over time with 36 extra enemies that didn't exist before. This is the second largest enemy mod for Amazing Skill ever created. (Yes, I have checked.) I highly recommend playing the original before even attempting this game. Good luck!
That evil looking play button to the left of the normal one is for INSANE MODE! It will cause enemies to spawn twice as fast! Watch out! There are 15 extra songs in this game. They are from 2 games called Rolling Sky, Donkey Kong Country Returns, Toby fox, F-777, Exit Path, Drive Ahead, and from Placeboing. The extra player costumes were already there, just unused, so I used them. (Except the taco wizard.) Thanks to DANISON for putting in the time and effort to make the original. For the new enemies, I just copied existing enemies and changed a few things. DANISON did all the complicated stuff, so most of the credit goes to him.
