Thank you and rest of the very early play testers.
I've pushed an Update, hoping to have a more Clear UI feedback about the game progression.
The White Arrow shows the progress gaining, and the Red Arrow shows the loss of progress.
I also add a bit of description on How to Play section on the page.
Thank you again for a quick and swift feedback that allows me to fix the submission before the jam submission lock. Please try again if you don't mind.
