I had part of the minigame transition screen pillar stay on the left side of the screen which made the shield and whack-a-mole minigame difficult. My browser scale is 100% so not sure.
I really like the micro game format. I was impressed by the lack of repeats and how many there were. I guess my only complaint is that the visual clarity as it relates to minigames could be a bit better because some minigames I just didn't understand until I saw the minigame and some I didn't get at all, but that's difficult to do with just two colors. The shader is neat, are you willing to share what you used or did you make it yourself?
