A nice relaxing music would be a great addition to this game. Also, I think having less UI clicks to select levels would help the game's pace.
The core gameplay is well adjusted, you get just the time you need to trigger your immediate memory, well done on that!

Well done, I really like the fact that I can generate my own levels. Great idea!

simple but overall fun, the presentation/graphics were also cute.

nice game!  this is a good puzzle game,  I have to have a quick eye and a sharp memory  to uncover the right mushrooms,  cool graphics and simple straightforward controls, good replay value ! overall I enjoyed playing this game, congratulations! keep it up!
