Quite nice! I liked trying to optimize my abilities on the different minigames, especially the typing and simon says which I could get through quite quickly. I really liked the find the button minigame, it is quite satisfying the way it reveals the desktop behind it.
I think the simon says was the least intuitive minigame for me, it took me quite a while to figure out exactly how it works. I think if the light in the middle was red until the sound stops playing + the particle effect stops on the last light, it would really help, as it wasn't clear to me that that was part of the pattern. I also got stuck in a rut where I kept clicking red because I thought it was the first one, but then (what I now recognize was the correct pattern) would play. But I couldn't tell that the red particle effect that I had just generated was from me, not from Simon, and so I just kept thinking it was still the first item in the pattern and I kept trying it over and over. I think more clearly separating the user inputted lights from Simon's would help a lot there.
I think the spin the wheel minigame was the most frustrating one simply because it didn't seem like I had much control over the outcome, but I think it's reasonable to have a gradient of highly-controllable to highly-randomized minigames in the game. I think if the game ever had a mode where you had to keep dismissing minigames at a certain rate to make progress it could be an issue, but it seemed like the game would only throw a finite number of minigames at you before guaranteeing you would make progress, so this was not a problem.
I do think the overall timer was maybe a little long for the number of minigames that currently exist, but that's OK. I do think a way to make it feel a bit better would be to let the timer go a little bit if, say, there's only one minigame currently active.
All told, though, very nice entry. Enough variety to keep things interesting, nice graphics, clean polish.
