As I am being a experienced gamer. All the details and excitement about this game drew me in to be bent on playing it. However, the long-term wishes to play this game so to speak. Died quickly without a adequate challenge and reward system. So some of my play suggestions.
1. Their is no real story? Okay yes you crash landed, okay well you came from some other planet. So now you mine crystals to open portals to harvest energy for no real cause at all? Are the robots bored?
2. No actual quest or assignments to do, or to report in with any actual NPC. (no real reward? [exclusion of mist tanks that make no sense considering to even get the tier 3 mist tank you must spend over 1000CE crafting your items.])
3. I like the challenging factor to get items, but with no real way to make the items/recipes due to large amounts of energy being required . As well as large amounts or crowns to even get your hands on the recipe. The challenge was underdone with no real adequate reward to quench the hard labor put into achieving them. -----> Change this.<----
4. Without a proper challenge and reward system that has more than 3 task so Spiral calls them. This game falls quickly down the no longer want to play list. (no really a suggestion but a fact.)
5. No leveling system? this game was a brave attempt without a leveling system, to make up for a leveling system perhaps a greater reward program? Nope. This game leaves you hanging, and without a real sense of achievement well.... It sucks. However, it was good while it lasted, but no long term goals are found in this game.
6. In my short time of playing i managed to get all 4 star equipment, and see many others fall and quit playing the game. Why? Simply because to even get the equipment you go through constant boring continuous runs of practically the same things for hours. Then you buy the recipe, the ope look at that, you need to go do the same thing again and again even longer to get money to buy energy and to make the item. You get the item, you do the same thing, and look upgrade time but now you have to work even longer. So rewarding doing the same thing over and over again? Not really.
7. Bosses.. Their are only two? I'm not even sure if Vog is a boss, and if not there's only one, jelly king? I mean you should have different one, change it up make like each tower have their own bosses, and then make he gates even change in real time. Then just keep them all open, make them each their own individual worlds! with different levels of power within the monsters of that world! You don't have a leveling system, so integrate a new star system because it is to late to go back. Make the gates separate worlds, make each world more challenging than the next, make new star items up to around 30 stars, make crafting prices lowered for the current items, then have them raise only slightly as items go up, (absolute must.) MAKE A NEW CHALLENGE REWARD SYSTEM. If i was 000 and sega, i would just start the whole game over with these ideas and thoughts in mind. Why not do a little of what final fantasy crystal chronicles did on gamecube. Seriously though. Something went wrong in a game designers head when he spawned this game without a proper quest line / challenge and reward system. 3 task/quest for an entire game? I mean they aren't even real quest , i don't know what to call them.
anyway, a small voice from one player, with some major game renovation suggestions to keep some of your players that are fastly fleeting.
This is more of a players opinions that suggestions really.
