Yes, I have seen their talk before! Nuclear Throne was one of the inspirations for this game.
Thank you for the feedback, having the option to switch guns using the mouse wheel is a good idea, didn't think of that.
Gotcha on the weapon size! I realized a little too late you could in certain situations shoot through the wall, but didn't have the time to adjust it. Though in the end I thought it was fun to use it and even and made a level just to acknowledge it with the sniper rifle, I would like to think it's more of a feature than a bug haha.
Thank you!
