Brutally Honest Feedback:

**** LOADING ISSUES ****

Went into the game shows "Click here to play the loop", click Play Loop. Does nothing.

Check Chrome console:

  Initialized level with amountOfSteps = 8
  Not Ready Yet

About 60 seconds later after numerous times clicking "Play Loop" it worked.

You need a spinner/progress bar or some visual indication that the game is still loading.

**** UI / UX ****

What the heck does +22 more mean at the top? 22 remaining levels?

**** SOUND ****

Click the Speaker Icon - no apparent error. Check console:

  Uncaught Error: Sample not found: undefined
  at AudioLibrary.getSample (audio.js:56:13)
  at AudioLibrary.playSampleAfter (audio.js:71:25)

Wait a few seconds - click them again. They work. You've got some serious preloading issues that need to be resolved.

**** POSITIVES ****

I like the switchable color themes, and the sounds seem pretty decent as well.

**** CONCLUSION ****

At this point I just got tired of being a beta tester. I don't care if people use LLMs to make things. I DO care if it results in basic testing being skipped.
