well..

It's not very appealing in terms of visuals nor presentation of what visuals you have. That said, it's an addicting little game, and it inspired me to try and code a similar game by myself (without tutorials, because that's how i learn) and i did successfully complete it within a couple of hours. You should check my game out tomorrow when i upload it, as it was inspired by your work, after all!

Its ok but it need work

The game is nice.
But the start round button is annoying.
The sound are a little weird.
And usually the light sequence continue between each round they only add one new light. Its not a whole new sequence. Maybe add a little background or something.
Anyway keep it up mate

Kind of like some other thing

On the advice of my lawyer I have never heard of Bop-It but this game reminds me of something only little children play on car rides. Call me biased but I think the age of memory sequence games is over. Judging the quality of the game, you did well and I liked the "start round" feature; something remiss in other games of this type.
