I think you should at least get the 3 star samurai boss set and 4-5 star weapon to go in there anyway. The legendary assassin sword with poison or crystal sword is easy to get and enough for most of the main quest and hard dungeon excluding the garbage boss and composer.
The duck, once purchased, does indeed provide unlimited energy. The reference to a consumable IAP is specifically around the problem that if you want to play on a separate device it cannot be restored directly through the app or App Store and requires you to contact the game's support.
This is accurate, and includes needing to collect all treasure and chests, cross over all squares, and defeat all monsters on the level. There are some levels that You can only achieve a perfect score by using the wall breaker scroll to do so, and others where you need to use ice scrolls or Momose (probably inaccurate spelling) which is a spell that attacks the middle columns of the screen and dries up any water in those spaces at the same time. That spell is also important to finding the hidden 8-bit dungeon (I won spoil the details, but you can find on Reddit if desired) .
If someone has a twitter account, could he ask the devs to fix that ? I am pretty sure it wasn't done on purpose.
^ Kind of assuming they know about it by now, so whether or not it was intentional, it is intentional now.
I think I saw this listed in the feedback document the dev is collecting, so has been formally documented. I suspect it is far more difficult to change how an IAP is classified after release and sales have occurred than before release.
Agreed. IceAll will turn all water tiles into ice so you can walk across them. You need to use the spell before you start moving as otherwise you won't be able to draw the line across them. If treasures are in water you can use the magnet when close to them and it will pull them to you as well. The momo spell (I forget its full name) will end up drying up any water in the middle three columns of the screen. However, this won't affect water tiles elsewhere on the screen, and needs to be used before moving as noted above.
You can't. Sell them and clear space. The ones I generally run short of are falcon, the physical barrier and wall breaker. Anyone know where these tend to be more prevalent?
