If you were a dev, how would you make a game? I don't think I'd make a good vidya dev because I lack professionalism and leadership.
I made a simple racing game similar to old arcade racers, its pretty basic, but its also the problem that it offers nothing new so I will have to make up some game mechanic that makes it stick out more and more interesting.
Not him but (OP) I'd take suggestions for what I posted in the first post.
A "switching" mechanics where you can hop into a different version of the track that is much more difficult but also much faster.
Ie: take the "normal world" safe route or go to the "alternate world" that allows much higher speed but is both more dangerous (hazard, weapons, powerups, etc) and the physics change slightly?
