If you don't get the epiphany as soon as possible, here are some ways that helped me.
1. try to find a circular way around the cube to get a colour out of your way, even if it's long.
2. try to find "mandatory" colored blocks and paint them early, when there is no other possibility for an origin block.
3. when you have two colors left, paint the whole cube of one and try to find a path for the other, it's clearer. It helped me, hope this helps!
It's either too long for a tutorial, or too short for a game. I can see your goal to test the game and gauge its reception, but I feel I couldn't rate it as high as it would deserve because it's in the middle of the road. Do improve it by extending it and maybe by breaking the mission into shorter chunks with interim goals. And add a mission progress bar. It has a lot of potential for being a great game!
Usual copycat of many other MMO we've all seen too often on Kong. Slightly better tactics with formation selection but not enough to warrant a 2 star rating, staying at 1 for all the usual flaws in these awful p2w that Kong features too often. Play only if you like wasting your time.
Finally,
There are some mechanics that seems dubious. Getting 3 picks out of 5 and not getting the special prices (horn and item) but the consolation ons (greem gems) has a probability of 9.9%. It happened to me 16 times out of 20 tries during "dungeon", with a 12-attempts long losing streak with a probability of 0.000000000089%... Color me unimpressed and I am suspecting an attempt at money grabbing...

Story-wise, it's not better. There is very little interesting coming out and you'll find yourself repeatedly clicking through it without feeling very engaged. NPC commenting out-of-character as in "wow, you have reached slash level 2" is kind of dumb... They could comment on how your fighting skill had improved without refering to gaming stat...
Situations get silly as well. Being surrounded by high-level guardian of order trying to fight you to assess your skill and suddenly being said that a damsel is in distress... right on the other side of the street? What kind of heroes are they? Most missions will be like this, and lead to a fight that should be AFK'd anyway.

The game has several flaws that make it extremely unenjoyable. Its main draw is the current sweepstake, and as a word of warning to the prospective player, know that getting the achievement for level 35 is much longer than getting from level 2 to level 20, so think carefully before spending more time than necessary.
Graphically, the game is quite nice, even if I get a strange impression of deja vu out of the graphic ressources... What is pointless is that the artists spend more time drawing breasts than anything. I am not offended but I find it quite childish to depict every warrior woman in chainmail bikini...

Is there more to this game than cardfights where you don't control anything and clicking go? I have tried, apparently ended the tutorial, but I still don't see the actual game... :(
Went away for 30 minutes for the idle achievements, and unfortunately my save is gone. Didn't run CCcleaner or anything like that, just closed my navigator... Too bad. I liked the "because you'll be back?" joke of the tutorial, but unfortunately, it's the data that's missing... I'm not sure I'll start over.
