This is very fun, the theme is well incorporated, and the shooting is very satisfying. But, walls appearing without any telegraphing when you're about to shoot a bunch of guys makes it kinda frustrating. Still, it's a 5/5 for fun and theme.
Thanks for the feedback. The same feedback regarding the walls came back during play testing, but I didn't have time to make it more apparent. I've added more information on the itch page regarding the Wall Timer and where/when the walls will spawn.
