Wow, those were some incredible graphics! Everything felt very clean and what you might expect from AAA game.
Also, loved how the characters said funny things when you shot them.
And the "Press [E]" to interact prompts were very helpful
My biggest suggestion would be to add some narrative/intro to introduce the player to the world and what their objective is.
Another thing: I wasn't able to figure out how to switch between guns? Tried the scrollwheel, numbers and tab, but never was able to switch off the banana shooter - when I pressed tab, I got a wheel, but couldn't figure out how to select a gun?
Last thing: movement felt slow, I think it would have been nice to have the player move faster?
Awesome job!
