The XP Stuff works, I just didnt put an explanation for how it works. But basically, Enemies killed drop XP it can be either 1XP (Blue) or 5XP(Red) Collect the XP drops then head on over to the Synthesis menu, its between the Inventory and Leaderboard icons, It looks like a star. Craft the desired item given that you have enough resources to do so. 

Once you have successfully crafted an item, head on over to your player inventory and "Use" the item to gain the effects of that said item. Go try it out

Thanks for playing and also thanks for the criticism

Thanks for playing, really. Ah that was an oversight on my end to be honest but I was short on time to add explanations. I was close to canning them all together like I did some other stuff. But basically, enemies killed drop XP. The bigger enemies: ExoHuskusGena and Neo-Nephites drop 5XP and 5XP twice respectively. Everyone else drops 1XP each. Crafting can give you debuffs such as Buff ATK and Buff DEF which buff Attack damage and Defense for your player respectively. You can also craft health potions and the mother of all: QUAD DAMAGE which buffs your damage by 400% ! Cool right. 

Again, thanks for playing my game. It means a lot to me. Cant wait to play yours (When they fix my net :D )
