It was just a suggestion, players may get bored of always failing, as some could have a good spatial observation and other could not. But this can only be seen after testing with a good number of players. My suggestions does not mean that it has to be available for all the game, you could have easier levels where you can get a bit of help. once player gets good at that, then the aid is not there anymore. My suggestion was more like the player to have a bit more of time to assess, not necessary to be able to lower.
