What I've learned from developing this game #1

• Don't use Unity's post-processing effects.  They eat your FPS.
• Try to add sound-fx as early as possible, because you will never have time for them in the last day.
• Don't forget to add basic things: menu, restart level button, instructions.
• Tell the whole story in the game, don't just depend on the plot posted in the game page.
• Unity.Input is poorly implemented and laggy.

Next post, I will be talking about level design that revolves around mechanics.
