i like the dual weapon flow and the fact that the enemies move more realistically (something like: move to a random point relative to the player) managed to get to the game crashing point at wave 3
the two weapon type work like "the one you want to use but cant very often" and "the one you dont want to use but it can be used for longer"
I'm not sure if there is supposed to be a boss due to wave 2-4 crash
and i didn't witness the player change/didn't notice (stated in how does this fit the theme)
