As this was my first game jam I learned quite a few things...
I myself learned a quite important thing, people will judge the game only based on the start, no matter how much you put in end, if begining is boring people will hardly reach till that part. As it is for my game, the real fun is when one enters the cave, but none reached that far, cause my beginning was seemingly repetitive... This is major thing I learned. (Thankgod I had theme throughout the game, or people would have not understood the theme relation of the game)
Second is the publicity which is major topic going in community right now (rate for rate) as one said PUBLICITY IS EVERYTHING!
Do check out my game if interested
