Reminds me a lot of one of the WarioWare Gold side modes where you play games back-to-back, this one is slightly different but still has a similar cool gimmick and I had a lot of fun. My highest score was 60, biggest pain for me was not knowing the trivia and having to just remember the answers.
The minigames were quite fun. I did get stuck on the cheer game for a while that I only figured out after checking other reviews. It’s a place where the lack of audio really affects gameplay too, because I had no victory fanfare to tell I was doing the right thing.
Two suggestions I have, one is that I think it’s worth putting the controls outside of the game window. I had the control icon completely cover a piece of merch once and didn’t realize it so I lost a life, plus there’s already a lot of unused space in general. The other is that having to dual wield arrow keys and mouse together (i.e. doing quiz and advertising together) is more uncomfortable to switch to than the other combinations. I get only certain games can line up anyways due to the gimmick, but I think that one should be edited or not be used because it felt awkward to me.
Great work overall!
