Challenge mode and Developer mode (18 Dec 23)

the game is now almost finished. i've most recently added and playtested the Challenge and Developer modes.

Challenge mode unlocks after beating the game normally (up to and including credits), and allows you to perfect individual level times. it's a neat diversion that offers some much needed replay value.

Developer mode can be accessed with Esc -> Game Menu: it allows you to reset the save file, starting anew to grind for best times in the Challenge mode.

that's about it for this update, two big changes. hope you are well and enjoy this little Xmas gift from me.

oh, and the source code is on github (MIT license): https://github.com/verysoftwares/secret-santa

edit: you can now reset the save with Shift+R during the gameplay sections.
