Like they said in an old flash parody "In today's episode skeletor chased after too much power, don't you chase after to much power or i'll come after you TOO !" XD
Okay so dumb jokes aside this is really good and i really like the spritework as well, plus the music really sells the atmosphere and this put me in a sorta vibe of the first blood omen game in the sense that, you may be the protagonist but you're not the good guy.
Even though gameplay wise it's not related at all, your game also brought back fond memories of playing Heroes of might and magic 2 when you have a necromancer character and each battle earns you the bonus oh having the enemies revived as skeletons joining your army :p
And i also like the fact that you didn't seem to put a cap on how many skeletons you can have, and this is awesome as you really feel like you're having an army more than just a group of summons.
Really did not have any particular issues with this one, so i don't know what i could say more.
Congrats you did a good job :)
