Hi, thanks for trying my game and for your feedback!
About the drink being ready to be served, I tried to do something by playing a slower "filling" sound effect, but I think if was off by like 4-5 frames... Sso the actual "full" timing happens before that... ^^'
At one point I even stopped the sound effect altogether, but it didn't feel good.
I should've been a bit more careful about the actual timing, and maybe should've gone the same route as the original arcade game, by just using an animated sprite.
On this build the levels don't really matter much, it's just a faster walk speed and spawn rate, you didn't miss much. ^^
Have a good one !
