Well done
Nicely done, well animated and so on, not that the animations are that very complicated, but still.
You should, in my opinion, either change the music to something original (or rarely used) or atleast get a higher quality version, it sounds like it was copied with a microphone thru speakers :S
Run all the text in the game thru a spellcheck, there where ALOT of errors in there that shouldn't have been.
Maby add some more abilitys for the last rank of units, like the Knights, should be able to either attack everything behind the main target, or have alot more health and act like tanks, atm they are pretty.. meh...
The wizards should have abit more damage and the cast time reduced, but have less health, basically, make them glasscannons, 1 hit dead, but while they live they are a massive threat.
This is something that people spamm over every game, but it might be needed for Leon wars aswell, more upgrades, for instance, add a special upgrade for each unit, to add armor/health/damage/speed and so on.
You could even add some random pointless upgrades and it would add some more playtime, like changing the colors of the troops, or adding a banner carrier as a 7th unit, boosting all your units damage by X.
At any rate, well done, but don't forget spellcheck!
