As it turns out, my unusually optimistic outlook on doing the Ludum Dare was completely unfounded. That's what I get for trying to be optimistic for once. Lesson learned, though - next time I should only announce my participation after the theme is selected and, what's even more important, after I come up with some decent enough idea for a game involving the theme.
After spending a whole day trying to brainstorm anything, I haven't even opened the Unity editor once. It was pretty obviously pointless, so I am dropping out of this one.
All the ideas I came up with today were of two kinds. First one was pretty crap, too complicated or simply unfun after I've started writing it down. I went through a few of these and scrapped every one of them.
Second type was just to do whatever basic thing comes to my mind anyway - probably some sort of Super Mario Galaxy ripoff with spherical gravity or whatever.
That's okay to do, but I know that I'm not a decent enough artist to produce anything sensible in a small time window like LD requires. Yeah, I know, programmer art is supposed to be enough. It's not enough for me, which is what matters most. Especially when I browse Twitter afterwards and see all these amazing looking games people are making.
So, since now I have only about 24 hours left (which would include sleep and other things, so realistically it's more like 10 hours), it's quite pointless to continue trying to do anything, really.
You folks have fun, and I'll spend the rest of the weekend playing Witcher 3 and Overwatch.
