I've gotta say, you did actually cover all the issues there was, but to be honest I really enjoyed the game. The issue I have is trying to play it on a web site, there is an automatic crash icon, and apparently it only works on some versions of google chrome. So I'm not sure if that's a coding issue or just the web site. I did get lost at one point in the plot, and it had something to do with the scene when the MC was kidnapped, I didn't know what to make of it. You couldn't really tell when the illusion stopped, even after escaping some how, I still had to question the MC's fortune. I think there are side stories to explore, one being the alternate dimension he discovered. Also the knowledge demon, I think it's unrealistic, that you basically offer an entire library and still have to pay for the spells. I like to encourage developers, because I know first hand how time consuming, and frustrating it is to complete projects, especially if it's a small team, or a one man team. I've only managed to play the first game, because there is a major issue all over the net with continuing with the saved file.
There are some more characters that was neglected, like the bully at the start, what became of him, a rivalry like that is bound to carry over into the story. Mida is also one of them. Also there was a major bug in the game, I do believe it was the snow scene, I travelled back and forth, for a hot minute before I was able to progress. So that needs looking into. Also the decisions you made in the past, you should have some ability to collect on debt or favors, based on your choices. An ex is Def Jam fight for NY. You can basically conquer , and after taking control. You can choose to build your team, and fight. For the war scene, I believe that the MC caught up to the Leaders a bit too quickly in terms of strength and respect.
In all my rambling here is my 2 cents.
The bully from the school, should have been incorporated.
His inner circle or friend group should be there, including the animal looking character.
Mida needs a character building Arc.
Needs the opportunity to control, or manipulate more characters to aid you in upcoming wars. I.E the vampire saga.
The knowledge demon and the deal that was struct has very little to benefit the MC.
The plot armor needs to be removed from some of the characters, decisions should let some of them die in battle, if you made the wrong call.
There should be more temptations to use the power of the stone, that can gradually increase the corruption. I.E if your life gets to a point or at some special conditions, there is a rage, or transformation trigger that can be activated, The longer you are in it, the more likely you will be able lose the character.
As I stated I've only finished Act I
So ACT II I will certainly let you guys know. But I still give it a 4/5
