Quite fun. I like most of the minigames, although I am not a fan of the lucky wheel. To me it feels like the hardest minigame by far, and for a long time it wasn't even clear to me how to win it (I'm not sure why I need to land on the yellow and not the green), but even once figuring that out, the ticker spins so fast that it is difficult to tell where it even is (as it's, like, visibly jumping from location to location between frames). So, my actual performance in the minigame scoring was mostly determined by whether or not I got the lucky wheel past, say, minigame 3, which felt a little bad.
Besides that, though, I really enjoyed playing through the minigames and feeling the energy in the room visibly increase when I played them. The barrel section itself is also quite fun with good music, and I find the 3D graphics quite charming. Launching off with a high score also feels quite good.
I think my best score I launched with was 14, which did not get me thaaaat far into the level, so I'm not sure I'm beating hardcore mode anytime soon. :P
I think my favorite of the minigames might be the match one, as the downstroke motion feels quite satisfying to get right. But, really, most of them besides the lucky wheel were pretty enjoyable.
Good job!
