Well, I've been steadily beavering away on the latest (admittedly small but useful!) update to the game for the last few days, and I've now got the logic in for user levels deletion / maintenance!
There's now a new DELETE LEVEL icon in the EDITOR screen, which will become active/bright red if on a USER created level.
I've also added a whole lot more functionality behind the scenes, to make adding levels even easier, including auto-sorting of the levels displayed, cleaning up of files for deleted levels, and lots more!
I've tested it in pretty much every scenario, and I'm satisfied that it definitely keeps user levels and data safe, while removing all redundant files to ensure no issues occur with old level data, saves, previews etc...
NOTE:- As this DELETE button will INSTANTLY delete a user created level, I want you to be SURE you meant to do it!... :D
...hence, a simple mouse click will *NOT* delete the current level. For your certainty, you have to press and HOLD down the RIGHT mouse button, and while holding that, click the LEFT mouse button on the DELETE button. You will hear a nudge sound if you didn't do this properly, and a different sound if you did!... :)
Give it a try! - the update is out NOW!
Oh yeah, I also added a couple of new levels / PUZZLE MODE layouts, Levels 105 and 106 - they're seasonal ones, if a little early!... ;)
NEXT UP! - Level sharing functionality!
...it may not be the most straightforward compared to Steam workshop, but I think I have a way of saving a level (or levels) out, which you can then send/share amongst friends! - The game can then simply import them in, if it finds any new levels in your game install folder, and add them automatically!...
