Ok so im doing this as i just found out this game dose have controler some support.

And yes i know it a controller and the pc master race dont like them but thats the joys a being a pc gammer you have options that consols dont. besides its quite nice to sit back and relax with a controller sometimes. :)
Any ways rant over :)

To activate it in the earth explodes and keen must die
1. plug in a controller
2. launch epidsode 1 or 2
3. press f4 and follow the on screen instructions
4. just a quick not as to what buttons relate to what controll ( button 1 is a button 2 is b) (x and o on ps)

Now for the other episodes
secret of the oracle
the armageddon machine.

1. so plug in your controller launch either of the episodes above
2. on the main screen go to configure
3. select use joystick 1 follow on screen pomps ( button 1 is a button 2 is b) (x and o on ps)
4 when done select use gravis game pad follow instructions to how you want the game to work :)

I use A as jump B fire X pogo Y status

Hope this helps with everything and you can now play all episodes with a controller.
So sit back and relax on the sofa or couch (as you yanks like to call it :P) and enjoy playing the greatest platformer in the world :)

p.s if i would go and add print screens to this i but its prety simple to do but if you do need help ask :)

ok so as of 14/12/15 or 12/14/15 (for you yanks and your weird way of righting the date) lol

Keen turned 25 i just found out that keen started off as a pc port for super mario 3. =O i know sounds made up but there is a video on you tube carmack released of the demo :)

The reason it never happend
Nintendo did not wana go in to the pc market.
So ID software made Keen.
So there you go you got an intresting fact that keen is the love child of mario not coming to the pc.

Hope you enjoyed the guide and the little fact. :)
