I wish there were more stuff to do! Though It is a wish list for future improvements because we all know this was in 7 days :)
I like fast pace minigames, but my feedback would be to give some instructions. (Maybe I missed something). Wario Ware for example, always give you one phrase or word to know what to do. I did not get what I needed to do with gears, but the visuals helped me “Oh I am oiling the gears”. :)
I think the core concept is nice and can be worked on even more :D Well done!
