I made the multiplayer works well with hamachi,and i and the tester were online on the server.
Beside the weird ai npc chasing our characters,we could at least try to move the character online.
And more,the latency was very small.
Here a photo of the gameplay.
By the way,he said he got a crash during the battle,i'll have to investigate what's up,also,i have some work to do,like making the Test NPC stop being a douche.
By the way,'till next news.
