Quick impressions for Defender's Quest: Valley of the Forgotten:
I put 4 hours into it, rather than waiting until I'm done (because this appears to be lengthy) so I won't get too extensive with my review. That said:
This is a tower defense RPG. You heard me. You play the Royal Librarian (default name Azra) who, after contracting the plague, has the ability to straddle the worlds of life and death and destroy the bodies of the ex-plague victims (Revenants) once and for all. Along the way she meets six characters, each representative of a recruitable class. The RPG part comes in where you can buy weapons and armour for these characters and have them level up with experience, but also boost them to higher levels during the battles (oh, and in case you're wondering, the tower is you yourself.) You can recruit as many more people as you like with your acquired scrap (money,) but you get achievements if you just use the main characters. Speaking of achievements, this seems to be one of the few games that not only doesn't penalize you if you make it easy on yourself in the options, but encourages it! And with that, I seriously recommend going with the 300% experience boost with no penalties for failures. Otherwise it could feel grindy.
Graphics-wise, keep in mind I first played a demo of this game on Kongregate several years ago, so don't expect much in that department. Music is good but you probably won't notice it too much as you try to keep up with the pace of the game...or maybe that's just me cause I set it to 4x speed. Gameplay is solid, difficulty is up to you: you can choose from four difficulty levels per scenario and go back to play the harder ones later. If you play through on "normal" you'll actually find it easy to challenging.
Best part: getting the Facebook reward anyway after repeatedly refusing to like them on Facebook!
Worst part: Some achievements don't show progress until you're totally done.
The verdict: Well let's put it this way: 98% of the over 1,000 reviews were positive AND it's got a recommendation from the IndieGAF Curator. It also has a free demo, so if you don't want to take my word for it that it's very good even if you're not a big tower defense fan (and I'm not,) then play for yourself and see!
