I'm uncertain as to exactly what's wrong with it, but minions don't seem to work properly. Adventuring with minions sometimes refuses to actually bring active minions along.
I realise that I could probably have done it the "expected" way, but there's a way of sequence-breaking on level 12, which I discovered on my first try of the level. It allows you to skip the orange key, and might remove a significant portion of the difficulty.
Not quite sure what the issue is, but I'm getting about 5 minutes of playtime before Flash crashes. As I say, I don't know whether it's on my end or on the game's end, but it makes me sad.
It's more difficult to get the combinations that specify multiple of the same symbol. So, for instance, Fondue (cheese, sun) is easier to get than Twin Stars (two suns). The reason is that you have more chances to get cheese OR sun than sun.
I found myself genuinely having difficulty with the spatial thinking aspects of the game, which is quite strange, because I'm usually quite good at that. Kudos.
One of the things that gets me about all these people who ask for a "next puzzle" button is that the puzzles don't HAVE to be done in order: that's actually part of the point!
My goodness, but shouldn't following the laws of gravity be part of a gentleman's code? After all, surely a gentleman always follows the laws?
Also, this business of having to adjust your perceptions to match your orientation is a dashed annoying thing to have to do...
Once you understand the game, it's interesting, with plenty of strategy required. Sadly, the tutorial doesn't really explain it that well, so it took me a few levels to work out how to actually play it well.
As has previously been stated, the grammar is a little off, and the story could use some improvement, but overall it's a pretty good game.
I found a glitch:
Change equipment at the exact moment when you change rooms, and your characters fail to materialize on the other side. Made easier to replicate with a laggy machine.
