7/8, 100% normal, 16% hard. All of the quests are easy, only OCD is a bit boring (because of it's length).
Because stats and equip are shared through modes, the game has somwehat low replayability. Hard mode is just run for (or because of? :P) OCD.
One tip: crafting is way too OP. On the other hand, upgrading is completely useless.
What do I really like about this game is, that even though it is "buy crystals, support devs" game, you don't have to buy anything nor like/follow anyone; you're given really enough crystals through the game itself.
I have the same opinion about the hard mode. Since you have all the equipment from the previous game, it makes it so much easier and repetative. But this game has a potencial.
The fastest way to beat OCD is to quickly raise your item level by crafting legendary items. It took me just ~10 craftings to raise my item level from 100 to 999. So don't be afraid to spend some crystals, it's worth it.
Let me explain my question better.
When u are crafting, u have on each item a number on a corner that I suposse is the level of the item, OK so as I think, if you take/buy a level 50 laser, on the next crafting there will greater levels of laser (if there is any), but this will be independently you take uncommon or legendary craft.
Then that's the only way I see, but it could take ages! There should be another way that I'm missing.
@vanerosa: The levels are the same for the different rarities of crafting. The only difference is bonuses from rarer items. You can get up to 4 bonuses at the highest rarity.
My current favourite weapons combination for the hero is laser and thunder. The laser can deal with the bigger enemies whilst the lightning can deal with those smaller little eyeballs and stop them crashing into your ship.
The thunder's also handy for getting under certain enemies and frying them from the safety of their underbelly. Also great for bosses that move around.
