The movement and guns feel really smooth, I feel like that's the most important part for a boomer shooter so that's good. The only issue with movement I spotted was that I couldn't jump while I was next to something (it happened with one of the tables for sure).
Some minor complaints: the jump sound gets annoying if you spam it, I need to have some feedback when I whack the walls with a melee weapon and more projectile enemies please. Would also prefer if the walker had a more interesting attack pattern, it just keeps shooting at you forever, even behind cover sometimes.
