Hello there!
Glad to hear that the tutorial did the trick of showing the mechanic, although in hindsight I feel like it would also be nice to show a guide in the main game. Will add to the list of things to review.
And by statistical differences, do you mean the damage and health of enemies? I ran out of time to properly add more curses, but some would have made the gun shoot faster, vitality up... but making the enemies healthy as well would have made them harder to kill... oh well.
Thank you again for playing!
