Very fun like the original, I love the new characters give more options to game-play, I personally love Umbra. I haven't played though all 3 fully in the game, just really beaten it with Umbra..I have to say. Addicting, not too long, nice a-range of enemies....however. it does have a lot of bugs. For one, the robots that can attack every enemy in an room. I mange to get 4 of them, and as soon as I enter the room, I am already victories. Even the bosses....little op little guys. There's some lag issues, even on lowest quality. If lot of enemies, I can keep attacking..just I have no idea what I am doing. Not sure if just my computer, but it is an troublesome espilley at the end boss. There's also an really really bad glitch with swords. If you get an sword that has 19 or higher, you won't be able to equip, sell, or move it. Shame you can't have an great sword at the end of the game.
Other then that, I think it fully enjoyable. Can be creative, and different strategies. Even though you get like..200 in states, it's not really that op. The game enemies, and level-raising are good balance of each other. Though I image anybody other then umbra would be an extremely beastly at the end game. The music is good, but sometimes it stuns me this game has it. Just the art-design makes me think of..something cuter, but doesn't stop things being epic.
It has a lot of improvements from originals, and can be still improve more, I hope there's an 3..but well, the first and seound one good en ought. Even of bugs, it still fun game and deserve an high rating.
