Thank you for your kind words and feedback, it's much appreciated. The weapons do have a slight pitch shift, however it may need to be increased. Weapon audio has been the main criticism I've gotten so far, so I plan on doing a total overhaul on the SFX soon to address all of that feedback.
I will also look into your other suggestions, I did have push back on the shotgun at one point but it felt overpowered, so I will likely revisit this to try and balance it out a bit.
I agree about slide canceling, so will look into this.
Thanks again :)
