Where to find help on level design?
A few days ago, I got a very honest and harsh, devastating but helpful, critique some days ago.
I thought I had finished the game and "only" had to bring it to more platforms and do marketing, but now I know I have to redesign and rethink to make the game fun to play so that players will stay longer than 4 or 5 levels.
I already have more complicated mechanics in later gameplay, but noone sees these if the players jump off early.
I have some ideas about new mechanics to make the game more interesting, but I am not sure in how to make interesting, coherent levels with a good gradual increase of complexity out of them.
I need help from a level designer or at least some material to learn more about level design.
