In this update I worked on some general items to improve weapons and keycards and how they appear in the inventory.

The player can now press "I" to bring up the inventory at any time, showing them the keycards they have as well as all the weapons they have an how much ammunition each weapon has. Previously there was no real way to see this information.
Along with the the player can now also see these inventory items while in the shop menu, which helps with buying ammunition for the correct weapons and not having to guess which ones are low on ammunition.

This update also introduces weapon scrolling. Previously the player has to use the numerical keys to switch weapons, now they can do so by scrolling with the mouse wheel. This helps a lot in combat situations where the player needs to swap weapons quickly.
Lastly, the inventory now also appears whenever a player picks up a new weapon or scrolls to a different one.

Overall this update is quite subtle but adds a big quality of life improvement and makes the general gameplay better by allowing the player to always check their ammunition and which weapons they actually have.
Let me know what you think and how the update feels!
Happy hunting, Operator8!
