Thank you StefanosM for your review on the game! I'm happy to hear that you took another try at it.
I am aware the ending is anti-climactic, it was pretty much nothing short of a toss-away scene that I created for the sole purpose of letting the player know the game had ended. The original plan was to let the other NPCs escape as well, or perish one by one while you explore, but due to time restraints I had to take that option out. I might revisit the idea after the contest is over and we are allowed to edit our games once again.
I'm happy to hear you liked the spike puzzle; I know the representation of the hints was not ideal, I'm still thinking of a better way to represent it to the player. I am also kind of honored to hear that you actually tried out the LEGACY mode as well, although it was not necessarily well-made in any way. I might implement some of the riddles found there over the main game some day, if I find a good place to put them in. The fox-goose-corn puzzle was a pain to implement, and I kinda gave up on some meaningful flavor texts when you did choose wrong, but I will revisit it one day. I'm not aware of a way of representing the puzzle in any better way than it is currently, but I should probably inform the player beforehand that the puzzle is a sequence of answers.
Considering the response of the doors in the LEGACY mode, of course I'd like to create a better response to the player. Your idea is good, albeit a bit cliché. As for the answers, they are case-insensitive, so for example if you wrote "MIRROR" or "mIRRoR", the game will consider them both the same answer. (they are compared to lowercase)
The computer is not necessary at this point, but you might get some bonus points if you manage to answer the password correctly. There is still the off-chance of crashing, as you mentioned, but it seems that it happens only sometimes. I will take a better look at it after the competition ends.
