In my case I didn't experiment with the mechanics or anything like that, but had some failures in time management and planning, I started working on a platformer based on DuckTales, spent near 3 days working on the sprites, then I realized it was too much time and if I kept going wasn't end like I wanted or even wasn't end at all, so I changed to a new concept that ended in the game I submitted.
In my next jam i will spend a few times before start working, making a schedule and planning everything in advance.
Also, i'm using all the feedback you guys are giving me to improve not only the game, but my skills, all this helps me.
I hope you guys share your experiences with me, and if possible rate and give me feedback about my game.
