I'm level 11 now, and from what I see, this game is only a slooooow grind. The only real way to speed it up is to spend real money on better weapons. Also, I don't think any armors can be bought without spending Kreds. So no, I will not play this game.
The battle system in this game is terrible. To start, you can't see your hp at any time other than in battle. Second, hp regenerates VERY SLOWLY. Third, THERE IS NO WAY TO RECOVER HP. Come on... This game sucks.
You get major lag in this game because you get 20 enemies on the screen, each with 5-10 arrows stuck in them. If the author reduces the objects, then people will get less lag.
