How unfortunate events lead to great things:
When we started the development of Solar we wanted to make a game where the player had to keep a fire alive, we weren't sure if we wanted it to be a torch or a bonfire but that was the basic idea (apparently pretty popular)
In the end we settled on doing a roguelike dungeon crawler when the torch dims out over time, the main character was supposed to be a humanoid figure or something similar.
Then, due to unfortunate events, we had to redo all the art 10 hours before the deadline, with an also unfinished game, and I was the one in charge of doing it.
Well, I never did any pixel art and I'm bad at animating stuff so my goal was to find something easy to animate and pretty basic. And then the idea struck me:
Why don't we make the character itself a flame?
I think that made the game a lot better and a lot less generic than a simple "dude in a dungeon", so I'm really glad that happened.
I guess the lesson here is don't let yourself be dragged down by problems in the project, especially in a competition like this when you have a short time to finish your stuff. Try to embrace them and go with the flow, they might lead you to something great ;)
