Monster World RPG ver. 1.1 is out now ! ! !

What's the code to the chest in Pirate Girl's room? I mean, I got the clue that I have to look at the paintings and that the titles probably hint at which objects I have to count.

In the room itself it's ambigious what actually counts as "LIGHT REFLECTED" - all the windows, only the big ones or all blue ones. I tried 2 and 5.
Next to the captain's room ("WHERE THE FRUIT GROWS") I would take the number of trees (4).
And from the aanchor room ("NATURE CAN HURT") the number of cacti (although they look rather like low plants with big leaves) - I counted 8, but some are only partially visible, so it's not clear-cut, too.

From my question you can tell that I rescued the first 2 girls and therefore got the means to interact with the "?"-blocks. I still think it would be nice, if the game aknowledged the possible idea of players that certain characters should be able to help with some of those things (I mentioned the blocks and the tiny doors in my first post).
For example, if Priscilla is in your party, if you check out a block, she could tell that she is able to reach it (fairy => flying) but cannot hit it hard enough or something.
And in case of the tiny doors she or Hotta might say that it's even to tight for them to get through. You could even let the hint at the actual method of getting through by the choice of there words (it still should sound natural, because the probably won't know how to to it exactly). And of course once they evolve, they are obviously too big and won't comment about this anymore.

Now that I also have access to spells the management of gears and genes sits even less well with me. Why do I have to unequip the current one and can't switch directly from one to another? It works for spells, too!

The sphinx dungeon I did not enjoy very much. That English is not my native language is probably a factor, but I could hardly solve any of the riddles by myself. Luckily they all seem to be copied fom somewhere else, so I found the solutions online easily.
I recently played another game that use this kind of obscure riddles as well, but it was less frustrating because there were several steps of hints the player could get. Maybe you could consider something like that, too.
(Also I have my qualms the most with the "2 sons, 2 fathers"-riddle because it's even more of trick question because of its ambiguity.)
