Or maybe the [2ND] or [ALPHA] key to do that?

@Builderboy
Did you implement a terminal velocity piece of code? It just looks like it.

Sweet.

Ah ok, you should post a faster one because to be honest I didn't watch it all the way through

I can basically do any part of helping with this, and would really like to. The only things I can't really help with is creating example codes and explanations for the codes and I wouldn't be able to do things relating to the code. But I can proofread, expand, edit, etc. everything others write and I can organize everything. I can also most likely put it into a PDF file. If I start working with Axe soon and get the hang of it and what the commands are I can then start helping with the things I said I couldn't. But would love to help anyway I can

So I tested it out. Great looking so far. Only a few things I found wrong, which most I'm sure you're aware of but just listing to be safe:
1. Can double jump and basically fly by holding ▲.
2. The collision thing with the roof seemed a bit odd. It would happen in some places and not in others.
3. When you click "New Game:
   a. You have the collision problem sometimes on the room (sometimes whole head disappears).
   b. Can apparently fall into the floor a little (only happened once).
   c. About 3/4 up the screen if you jump you can find ledges on both sides that are invisible.
      1. On right side you can jump and go off screen.

Glad to see this coming together

I can try to explain some later, if I manage to think of how to word it all haha, but Builderboy wrote a tutorial about trig here so that might help in the mean time. I really need some sleep so I'll try coming up with something tomorrow for ya

Huh, the only one I've ever seen is Bunny Gotchi. But ya, should be interesting. But we should get back on topic now
