Theme Implementation: 3/5. The time speed up feels adjacent to broken time, but not representative.
Special Object: 5/5. Microphone shooting sounds waves definitely covers it. Makes sense within the context as well.
Fun Factor: 4/5. A bit simple but short enough that it doesn't get tired. Not bad! The high combo ramp up is pretty satisfying. Just destroys all the notes instantly.
Gameplay: 3/5. There wasn't all that much strategy in the gameplay. Giving the jump a little more utility would have been nice. Maybe pairing it with temporary platform and starts within jump reach, but then raises higher, getting you closer to the notes should you jump on it in time. As it is, I just found myself spamming jump the whole time because there wasn't really a reason not to.
Audio: 5/5. Music speedup on combo chain is solid. And the slowdown on game over is a classic. The music selection itself is a bit generic/repetitive, but overall, the audio was very comprehensive.
Visuals: 3/5. A bit unpolished, but not bad. I don't love the purple and black noise pattern used for the background.
I'll remember this game for when the screen gets covered in sound wave projectiles and the detailed reviews its creator gives. Congratulations, nice game!
