Horrible controls, the game could be interesting, but with such these controls it's only frustrating.
Remember, a game must be something you ENJOY using...
Good game...but it will be better if the score refresh OR instantly when you touch grass OR while you kill enemies...because on the LAST stage ( i had only 2 "seeker" to update to reach 10 on all enemies ) I lost after a combo of 3000+ exp because the bar didn't refresh before the fuel finished.
IT SUX ;)
A bad thing is that the enemy cannot be destroyed by "friend" cannonball...that hits only me...it's not very realistic ;)
And this thing could help when game become more difficult in creating strategies...using a "close combat" ship as a shield...or something similar ;)
Too simply to beat...after you capture a capital ( or a city with "special units" ), the only thing you have to do is to use scrolls to heal your immortal units and watch...
It's a good beginning, a base for something that could become a great game...with some improvements like better quests, a "enchanting weapons/armors" system ( like Diablo II :P ) and a bigger world ;)
