Nightblade had ups and downs with me but eventually ended at a pit. I'll admit, with a little tweaking the game could be very good, but in its current state it's hardly worth playing.
Starting out is tough, the enemies are too difficult and there's no clear area to go to. Not to mention, go one screen off and get mauled by some extremely high-leveled enemy.
Magic in this game is broken. You can only add a maximum of 5 MP to your character each level ( and that's sacrificing everything else) and the basic attack spell costs 5 MP.
Oh, and did I mention that whilst you were putting all your points into MP just so you could cast a decent amount of times without drinking an Elixir (which only restores 10 MP by the way) you end up missing out on Willpower so you can even avoid missing with those costly magic spells?
Combat on the macro scale is charming, but broken as well. Adding dex upon dex point still leaves my character missing frequently, though agility seems to work well enough. Armor and Weapons are severely overpowered, causing strength to be an unnecessary attribute, and adding to HP to be unnecessary.
This combined with the lackluster graphics, the huge file size, and the large amount of "dead space" in the game make for a very unpleasant experience.
Gameplay: 6/10 (The combat is fun despite its flaws.)
Balance: 2/10 (Broken.)
Graphics: 2/10 (Only redeeming feature is the ability to add your own.)
It could be very wonderful with a little work.
