This game is by far one of the cleanest games I've played but there is one small issue I've came across and that is the inventory. others and myself strongly believe that your hotkeys/toolbar should be a separate inventory and not take up space in your backpack. The way it is now is just messy because you pull out your sword then pick something up and now when your put your sword away it'll be in a random spot.
Other issue on inventory is that armour should stay on your character when it breaks but just loses all the effects until repaired, myself and others hate being in a fight with a full inventory and not realising that our armour broke and dropped on the ground.
I also think there should be two accessory slots because you can't use badges without giving up a glider or wasting even more inventory space
