Making successful games on Kongregate and the World v1.5

this is a good undead thread^^
I'll update the list these soon.

WASD+touchpad was uncomfortable with older pc, which hopefully nobody still use them.
Some really old pc had the touchpad under the wasd keys, or without click buttons.
The general tip underlying is to think about ergonomics, and make the control easy to use(unless it's more fun the opposite)

Wow these are all good tips!  Anyone could make a successful game with these guide lines!  Thank you so much!

Thanks back and welcome!

I might add also some insight about human features, like reaction time, perceived colors and hearing responsiveness later.
