Puzzle Ideas (Research)

Here are some possible 'out there' puzzle ideas I have been researching. Let me know what you guys think.

1).  Pressing certain keys at specific intervals?

2). Quiz show type thing? where you have to answer questions that pop up on the screen to advance?

E.g. How many legs does a cow have?

A = 1, E = 2, C = 4, and you have to press the right key.

3). A special area could become available after the player reaches a certain point in the game?

4). Cat came up with the idea of having clues.

5). Time limit of how long you have to complete the game itself? Or you could have a time limit just for finding each A.I part?

6). We're already going along with hiding objects (A.I parts).

7). Toop came up with the idea of having "Swirly" objects pop up on the screen and you have to click the right key or number and it will disappear?

Feel free to add anymore that you think of :)

Cat :-
I think incorporating the hallucinations and plants into puzzles would be good, we had the colourblind idea, what about environment changes according to a plant and thats how you advance or  you hear a voice and have to decide whether it is a good or bad voice to follow? ,  i think when they said puzzles they meant in terms of , like spyro, tomb raider, lanoire, looking at your surroundings,
'i need to get from A to B, but somethings stopping me' so how can you over come the obstacle?
Using what we already have to our advantage like the plants can cut down on asset building and the possibility of very hard to find coding.
we can make physical puzzles like pushing blocks i think to do things, the planet doesn't have to be uninhabited , we could just make it so the canyon doesnt have any aliens there but there a some things like ruins and stuff so we can implement ruin type puzzles.
