Cool! It felt very polished and professional, and the diagetic UX was a really nice touch

This is nicely made and looks good, albeit not making the best use of the carnival theme. I don't understand the challenge as there doesn't seem to be a timer or anything to cause a 'game over'..? Smaller things to add might be:

* Something to show you need to wait before pressing the buttons (in game mode #2).

* Different leaderboards for different game modes/difficulties.

* Some form of background for non-passthrough mode?

It's a great start, though, and I like that it works in passthrough.

The game looks a bit dark for me but perhaps it is aimed to be use in AR ? Simple gameplay but I miss a bit of the fun part, especially with a funfair ambiance maybe.
