Doing a Wario Ware/Rhythm Heaven-like game for a 7 day jam is to have lost one's mind, I love it!!
I really liked how you managed to keep the artstyle constant to all the games. Some minigames really needed that instructions (great to have them at every moment in the pause menu, +1 for that) while others resulted very intuitive.
The microgame I liked the most is the alphabet one, both the list and the premise are pretty original :D
Found a couple bugs in the "candy crush" microgame, but nothing really important, probabbly happened because an unwanted double click.
Sadly, and appreciating the HUGE effort that goes into making that amount of music in a week, I think that's the weakest point of this game. I've ended up with a bit of a headache, and it's simply because of the chiptune without any kind of filter or effect to reduce its intensity. I also haven't found a way to lower the volume below 2, I don't like to play without music or effects, because I think it's breaking a little bit the creator's artistic vision, but I went to test if it was possible and I wasn't able to do it.
Still, I enjoyed spending some time playing your game.
We need more games like yours, good job :)
