Does anyone have advice for setting up a rat cage?

Hi! I have been looking all over online and in cage tour videos to find good setup ideas for a two story cage like mine but havent found much so far. We did get this cage second hand so im unsure of the brand but I know the middle layer cannot be taken out which I know most people do. Im wondering if what we've given them will be good for their entertainment and exercise since im quite new to all this. Lmk if any of you have ideas or suggestions!

Heres what we have right now (the top image is what it looks like rn after we've changed it around a bit):

Looking good! I do suggest multiple water bottles to keep them hydrated as well as maybe some more chew toys. This type of cage is good for exercise since they can run up and down but it’s good to still get them out every day, best of luck to you and your babies!
