I played on a PC in browser.
On first attempt, during the tutorial, I clicked the score upgrade before it prompted me to do so. When the prompt came up, I was unable to afford the next upgrade and was softlocked.
I refreshed the browser page and ran the game again, and it let me start over.
Tiny bug, game worked after that.
I like the sound effects, and imagine it'll get pretty beepy down the line!
