Thanks for playing! The enemy count does increase over time, but it is random which side they come from, which can lead some of them to clump together. You can keep the multiplier by hitting the ground. You don't need to hit the enemies as long as you don't attack yourself. The pistol was meant to time the arm better, so if an enemy came and the timing was bad, you could push it back to get better timing. Thanks for the feedback though! We will keep all of it in mind if we work more on it!
