Okay for testing purposes I just played this with Scet3 (who is likely to write a better review than me) so I can start mentioning the flaws I found.
First off, I can't help but point out you spelt "Witch" as "Which" if you mosue over them in game they are called "Which" stuff like that gets to me. Now onto the big problems. As said before one side has a CLEAR advantage as they can have their archers shoot flaming arrows first on the enemy archers and unless they get freak accidental luck with criticals you are going to have an advantage to the starting side as they will have archers while the others don't, even with freak luck it would only cancel both archers out. An advantage like this should not exist in the game, a simple correction is to remove the shooting potential from being all the way across the map and narrow it down a few squares so they need to move out to be shot.
Another problem is the Whiches (again spelling) are absolutely useless, I couldn't make them do anything and they get 1 shot by a knight just hitting them, then the wizards magic gets blocked, BLOCKED, none of the attacks get blocked in the game but magic does? For a game called "Knights and Magic" there is a sure lack of magic, unless you count the knights ability which they can use on an ally which is NOT TRANSLATED FROM SPANISH.
The coup de grace comes with the fact that we couldn't finish a match because Scet3 glitched out and the game refused to work for him anymore, it wouldn't let him cast any abilities and even when letting his time limit run out I couldn't do a thing. The time limit does not pass the turn over to me when running out, so I had to quit the match and the game kept me with a 0/0 win loss rate despite QUITING THE MATCH.
There is also a lot of other problems, like when a melee unit attacks and returns to their square they face towards their side and have their BACKS TO THE ENEMY, and in this state they don't even take any critical damage or any penalties despite showing their backs. Also when trying to do a move order if wanting to stop or do another they just cycle through wasting the orders of units I still want to act, leading to me having to redo them all to have what I want rather than keeping the actions the same unless specifically clicking on the unit to move. Also a final personal note the implied racism behind using a person identifyable as a dwarf or a hobbit / halfling to carry the flag due to their height and flexibility isn't cool.
There is a lot to work on, but it is apparently in Beta so you have time to do it, just make sure to take the criticism and work on it to make your game better.
