I was not at all happy when I found out the hard way that you can only have 10 of each consumable. And if you make too many, it lets you do it, but silently discards the extras. If only it would disable the crafting button for a consumable when I hit the limit of 10, it wouldn't be so horrible.
"Quick match will put you in battle against an opponent around the same strength."
No it won't. It always puts me in a battle against a computer opponent whose strength depends mainly on what tier I'm in. I got to the Pro tier before getting the Skuter chassis, so now it's impossible for me to win any Quick Match battles with it, let alone 50 of them. It keeps sending these big dragon-like things to fight my Skuter, which can't even make a dent in them because they heal faster than I can do damage, on top of having 3 times as much HP as me.
Auctions don't work. I won an auction for a Dodgy Contenda, and received a Mail message saying so, but never got the part. I'm not sure whether it still charged me oil.
Visualizing the shapes is easy. I never needed to draw them. The hard part is that there are about 10 shapes that hardly resemble what they are supposed to look like, and 4 shapes that require a 1-word answer when the obvious answer is 2 words.
I really hate how it tells me "use your mouse to move hujos" every time, sometimes twice in a row, blocking my view of the hujo tower that I'm trying to build on.
The 50x50 puzzle is in fact not solvable by logic alone. There is an ambiguous area where the 9th and 10th rows intersect the 18th, 19th, 21st and 22nd columns. There are 2 possibilities there that both fit the numbers perfectly, but only one counts as the right solution, so you have to either figure out the answer intuitively based on what looks right, or just guess.
Some of the puzzles are kind of hard, but I think the different sized pieces actually makes it easier, not harder.
I finished the "water cube" puzzle, but still have no idea what it's a picture of.
Level 25 has a simple solution that uses only half the command stones. I can't think of a more complicated solution, so I have no idea what solution was intended.
Level 28 has a much simpler solution than the obvious intended solution.
There is a rule that when multiple folds have been made, only the most recent fold can be unfolded. (I'm not sure if this applies in all situations, or only when folds intersect.) That may be reason why ToddPeak has a fold that won't unfold.
