Such a cool and funny idea! I like having 5 different minigames constantly changing, this definitely keep you on your toes and adds to the overall hectic feel of the game. I also like how different the games are, so you have to be able to completely switch what you're doing (mouse movement vs arrow keys vs typing), but they are also very visually distinct so you can easily recognize which minigame it is. Even with the glitches covering the screen, the most important elements of each minigame were still easily detectable. Overall, great job!
Also, that Stack Overflow joke image is hilarious and very accurate!
