Nice to see you reason some! You should do it more often, it makes you a lot more sympathetic

We've already been changing things to steering before eventhough there was nothing wrong with the steering per se:

-you can always run without caps-lock
-mouse support (not a very good one though!)
-JJM let's you reassign the ammunition buttons

At any rate the thread is about whether it alters the game play in a (too) negative way or not. Now you've atleast bordered on the topic. You say however that it's a good thing to make the playing experience more comfortable: this makes RF-climbing a more comfortable task. It doesn't add anything you couldn't in theory do before (even shooting two types ammo would be possible if you practice: one finger on jump, one on shoot, two fingers to press 4 and 5 a lot).

As I said above, the opinion that more easily shooting two types of ammo at once is too big an alteration is a valid one, but don't try to make this program idea out to be fundamentally different than what we've seen in the past.
