100 Rogues is a great game and one of my must-plays on the iPhone 4. I still encounter bugs from time to time but am sure that they will get fixed. Here is a list of bugs I'm recently encountering under version 2.9.4:
1. ever since the White Knight was introduced, I found problems with a non-functional projectile reflection buff (typically after reloads), and an "H" sign always hovers above the character's head as though some kind of debuff stays with the White knight. I think this will be fixed in 2.9.5 so I really can't wait to see how it's changed.
2. I also found issues with game reinstallation. The game got so buggy that I decided to delete it completely and reinstall it. The problem is, I wasn't able to restore the White Knight, which was previously given as a freebie, and I now have to pay $0.99 for it just to get it back, and now I can't even play with it because the game freezes everytime I tap on the screen when the White Knight appears!! It took me at least 3-4 game reloads before I could get back into the White Knight game screen but now I can't use it! 


3. With the White knight comes certain problematic influences over other characters. Have tried playing the Fairy Wizard and Tourist but the following things happen:
- "stun" no longer works properly – a stunned monster will wake immediately in the next turn and continues to advance at the same pace as the player as though it never got stunned. I can understand this from the slow and bulky White Knight's perspective, but Fairy Wizard / Tourist!? That sure is buggy;
- hunger speeds up like crazy, and this was not even after reloads. I remember eating a roasted food just before entering a Genie fight (not being "very" hungry yet), fought off the Genie in around 10 turns, went and picked up the spoils on the floor, bought stuff from the shop, went down to the next level (no dilly-dally in between) and within around 10 turns, I was hungry again! After eating more food and walking around in Dungeon 1, I was hungry again!! 3 of my Fairy Wizards died because of rapid starvation!!
- relating to hunger, at zero belly, all characters seemed to lose 2 points of health per turn as opposed to 1 point, just like the White Knight. An otherwise easy battle against skellies and skelly archers turned into a death match, as the rate of recovery falls behind enemy damage! 
4. Would you also clarify one thing - do White knights regenerate at all (i.e. without the regeneration buff), i.e. are they like zombies? The difference here is that zombies start out with 900HPs while white knights a meager 16. Not being able to regenerate at any rate makes it very hard to get past its first couple of levels.
Really hope that you will fix these problems (and if possible, PAY ME BACK $0.99 FOR MY FREE WHITE KNIGHT!!).
Thanks…
