Pretty fun, Nice audio i can tell that you took special care for the visuals,
But there's this one thing that's stopping me from playing which is the space key stopping to jump right after death (even tho i do have jumps left on me)
My guess is that there are 2 variables holding the amount of jumps the player has
(lets call them A and B)
A is responsible for displaying the number on the player
B is what is used in the game code to restrict jumping if zero
and then you must have hooked some code on scene loading and you only changed A forgetting B
that results in B turning to zero even tho A is not
And so i can not jump after death
the fix for this is not to use 2 variables in the 1st place
Again nicely done mate cheers
