@Damian666 Sorry dude. didn`t read the rule about language, as I saw that author was Brazilian I naturally wrote in Portuguese... I just translated it...
Just wanna congrats you, bro, about all the things that you placed til now in your game, is one of the few that we can find on this forum that is currently playable.
2 things bothered me a little, hope you understand as a constructive feedback:
1: Elf just seems to be misplaced on your set of classes, It is commonly used as race, not a class. Mabe, you should review your class set and change Elf by some other classic proficiency class like others that you use or change all the set of classes to be more coherent. For example (using Tolkien's universe races to implicit relate to proficiency/skill sets) you could have {Elf, Human, Dwarf, Maiar} as classes instead of {Elf, Assassin, Warrior, Sorcerer}.
2: Initial gameplay at beginners/tutorial island seems to be a little unbalanced as you take levels and distribute your attribute points and it doesn't scale with your weapons. You pass through the five initial levels causing the same damage and having same challenge to confront stronger creatures as at level 1, just the amount of life points change a little and helps to fight the stringer creatures. It may be a little frustrating to beginners and usually, mmos do the opposite, increasing lower level faster and doing more advantages at initial levels and the "power jumps" becomes less visible as you evolve. I saw that you have a big influence of Tibia but even on Tibia (old and good sandbox Tibia before tutorial introductions), you could experiment the difference fighting level 1 or 2 and so on as you change equipment sets even without getting level...
wish you all the best and I hope you continue motivated to improve and grow your project...
