Best advice, fail faster.
That may look like i am telling you to fuck off, but its actually the best thing to do as a budding game designer.
I could spend all day and write novel, on what is wrong, as there is so much wrong.
But i am not going to.
You have to figure out for yourself as no one can really tell you what is wrong.
SO many first time mistakes in control, panning of the screen, movement, conveyance, directive and objective.
So figure it out.
Experiment make the game as you want it and keep failing faster, to gain success.
P.S. Asset flipping is not cool, be original.
Good day.
