hey thank you for the detailed feedback! a lot of what you're suggesting is stuff i've thought about as well:
the glock has been made to shoot faster in the build that i'm working on, but sadly it won't be public since i'm kinda in the mud of AI rework and a bunch of other stuff etc. though soon there'll be some sort of preview build on my patreon with new stuff.
the smaller and more intricate levels like the combat warehouse are actually going to be little side things you can do while having access to the bigger and more open levels to make extra cash. should be fun, and in theme with the game's story, so don't worry there will be plenty of ways to engage with the combat.
as it stands rn, the AI is pretty bad, i want it to be simple and consistent with some randomness tossed into the mix and potentially group behaviours. in my head, the game isn't really a tactical shooter, it's a medium to throw around a bunch of ragdolls, so however i can, i'm going to try to make the AI be more dynamic and goofy to encourage chaotic violence.
also, i too find myself popping open the game to just run around and blow guys heads off. i'm still not sick of it somehow, though i do need to add a bunch more weapons :)
again thank you for the feedback!
