Thanks so much! Well done on figuring out, we've realised that how "easy" to get the game is depends a lot on the randomness (which, if you think about it, is a weird meta-feature of the game we hadn't realised while making it :D): basically, after a bit of playtesting, we realised that sometimes if a player has "bad luck" with the choices (especially if many wrong choices are are picked in a row by the system) it becomes obvious that there can't be any logic in it. In the "good luck" cases (i.e. only few errors here and there) the feeling of "there must be something behind it" is more supported.
Anyway, thanks a lot for playing! :)
