thank you for playing!
Good point, I wanted to make some kind of checkpoints and minor adjustments like the heart but sadly I ran out of time,
and for the hotkeys, it stands for the "Left key " and "Right key" it could be either left and right shift(which i recommend) or a,d and left-right arrow. I made that about 10 minutes before the deadline so I did not think that might happened.
thank you for the feedback!
