It is a nice game :D

Just a suggestion, but it would be nice to have some keyboard controls, like arrows in addition to the clicking.

Solid little game and a good music selection. I did have some initial problems at the start understanding the game. I think the instructions could be improved for us dumb people who try to overcomplicate things. I think I could leave the button light on until the next round, I was mashing the button multiple times at first (my fault for not reading instructions in the first place).

I think, as others have mentioned, a countdown clock would be helpful, is there any progression? i.e. does the time between rounds reduce?

Like the game page background design.

Overall I enjoyed the game.

I like the chill music and colors in contrast to the stress my brain is having to figure out the biggest number.

I figured out that there is a delay when I press the correct one, but none when I press the wrong one. So if I am right I can still change my decision and press another button, and if i am wrong game ends directly. So far I have enjoyed it, really nice entry!

I was a bit confused at the beginning, wasn't sure if I really pressed a button or not, but then I understood you select one and wait until the timer runs out. A visual representation about the timer would have been nice ^^. Overall nice little game.
