The minigames were super cute and fun, although a bit buggy at times. Being able to buy new minigames was a fun idea although I found myself spamming the same few over and over, maybe motivating the player to switch it up more would be nice. While I'm fussing over small issues, I think losing a minigame could have a bit more of an indicator as it just kind of returned which left me a little bit confused some of the time. Great job!
Side note, the voice for the tutorial and the music didn't play in Opera but did in Chrome, have fun figuring that one out (or ignoring it).
