BAHAHAHAH I also want to make anti-work games <3
I already laughed when I read your game's presentation. I love it ! I know it's "just" Tetris decorated with lore but it does the trick for me - and connects with the game's plot of playing while at work + managing time-table.
Also, everything works well. The only thing I'd change would be adding a music loop or playlist. But I get it the blank sound might be the stress and boredom from work and it does add tension to the game so it may just be me looking for an idea to give at least one piece of advice that may not be needed ^^
Thanks for the fun, I showed it to my (currently burnt-out) husband and it made him smile too.
