Designer for the project here, I'm glad you liked the gun swapping mechanic! Do you think there's a way we could change the punch to feel more satisfying for the player? If not, we can revisit the start of the game once the jam is over and reevaluate how the player is equipped at the start of a run.
To my knowledge we didn't have a ton of issues with choppy gameplay. Maybe something we overlooked or maybe it's a screenshake problem like you mentioned. Thanks for bringing it to my attention, we'll start looking for what the problem might be!
Glad you enjoyed the aesthetic, we worked super hard on it!
Thanks for playing and giving us feedback, it helps us out a ton!
