Fun game but some improvements could be made. For starters, I think adding a map with no pitfalls would be great if you're trying to fight to the death without accidentally launching your opponent to a cliff. Another great option would be the ability to switch your weapon's direction as some weapons are different when you're on different sides.
what abt an option for portals to be on either side of the island, and when u go through them u lose a third of your health and r teleported through the other one. pitfalls r removed but weapons that rely on them to win like scimitar r still usable, and if u want to u can now switch weapon sides for a price while still keeping the strategy of staying to whichever one is stronger against your opponent
