Got this game in the Steam sale and just finished, thought it was rather good.

Took me about 8 hours to play it, including getting all the secrets and a large amount of the experience (only needed about ~40 more to max my characters, think there was about 60 I didn't collect). There's some extended gameplay there, collecting all the experience.

As for the game itself, the story was decent, with some nice narration and artwork with the gameplay being a solid puzzle platformer with some nice special abilities and some decent, but not overly difficult, puzzles (it leans more towards platformer with puzzles, in the vein of HL2 rather than Braid puzzles). The graphics were rather good, colourful, detailed and with some nice effects. Controls all worked great and were rarely, if ever, frustrating. The RPG elements (levels and items) were simple and allowed you to adapt the game a bit to your playstyle, without making it overly complicated.

I recommend it if it ever comes back on sale.

It is a great game, hoping for a sequel soon. I wish that they would make the knight a bit more useful, as you could just spam arrows as the archer far to easily especially when she is the main platforming character so most of the time was spent using her.

I agree, I used the thief the most, especially with fully upgraded arrows and the item giving you a total of 4 arrows, she dominated combat and platforming (grapple was very useful). As soon as you had her fire bow, you didn't even need the knight to cut things. I lost more health using the knight than I did with the thief, aswell, as the enemies could actually hit me. The hammer was kinda good, but nothing compared to the bow.
