That game is not really worth it unless you are a die heart fan. Beaten this guy on the hardest settings in roughly 3 hours and 1 additional hour for unlocking all goodies: 4 hours and then this game is gone.
In general this plays kinda like Doom. Massive amount of dead stupid enemies are launched at you which are way too easy to dispose of especially in the hard mode. Main controls you can see with "START" and are D-Pad/Buttons by default. Although they are a couple of attack possibilities ( melee, short breath, long breath, shield, fury ) you will only stick to short breath and shield as they are the most effective of all.
One thing I hate on this game is the same I hated on games like "Zoids Dash": You need to use your thumb to dirty your screen. Sometimes there are stupid flies you can't attack else than literally "squashing" them with your thumb on the screen. The result is lots of dirt unless you figure out a way to minimize your own finger dirtiness or willing to clean the display sooner or later.
The boss battles though are good. The D-Pad controls your motion and the stylus indicates where to hit. Unfortunatly you look in vain for a left-handed setup. Hence all you left-handers out there are forced to use the stylus with the right hand. For me not a hard thing as I am kinda double-handed but others will have lots of troubles that I am sure of.
Boss battle is full 3D with you fly-circling around some enemy all time attacking him while he occasianally tosses stuff at you whereas story mode has the spyro typical ( for DS games that is ) 3/4 view ( or bird view, pardon me, dragon view ) but instead of collecting gems and various "objects" you retrieve colored shards from the badies filling up your experience points, health or breath meter. Experience can then be used to improve on of your skills of which there are many but only a few really usefull. Some enemies require the right elemental breath to dispose of them. Apart from that I always sticked to lightning as it is the most versatile one especially since the lightning shield turns you
invulnerable for 6 seconds. It is nearly impossible to loose with that one on in a pinch.
Various usable objects require you to drag a circle into certain directions to use them. Rather useless as a simple "use" button would have done the same job. But then there are the light crystal puzzles which can be some brain tester. Stylus is a must there as the picking and turning of the objects is rather cubersome. You need mirrors, splitters and prismas to redirect the correct light into the correct crystals to solve it.
Extras. You unlock them by collecting the white shards found in solved light puzzles. The game has a total of 40 for you to find which is not difficult. You can use them to unlock the extras which are an arcade mode, puzzles and cheats. Arcade mode lets you play the same levels again but this time the old way only jump and one breath attack. The rest of the mechanics are the same as in the story mode. After every level you get points for time used and accuracy. In the end there is a scoreboard for those who need it. Then there are the extra puzzles which are again light crystal puzzles. Solve all puzzles in both section to gain another 20 white shards to unlock the cheats. They are the typical cheats like god mode, heaving all skills or fun cheats like replacing spyro with cynder ( at last what goes for 3d-view ). More than that there is not to see in this section.
Is there lag? Yep, on one place there is ( at last in my playthrough it has been this way ). In the first mission on the ice hill the game crawls nearly to a halt. In all other places the game is playing fluid though. Not sure what they cranked up in that one there.
Even the few movie sequences and RPG style cut scenes can not improve the game and the extras are not really worth the time except for the puzzles but there a game only about them would be more interesting. Difficulty is ridiculous as you only have to stick to the lightning shield to be invulnerable for fully 6 seconds. I would give this one maybe 6/10 ( hence "for fans only" ).
Finally...
A big bad dragon fully pitch black,
Can you get more stereotype than that?
