Well, if I had an alternative for account activation at Regnow, I'd release the full edition on there. It may take a day or two before I can even get a chance to do so.... The part about contacting a representative shouldn't have to be required - it's very annoying and extremely inconvienient.

If you haven't noticed it, in the menu help area of the tutorial, the controls are given right there in a very quick form. It says "Quick review: key - what the key does". I added that for simplicity. I'll edit my original post to include the controls.

The feature comparison chart explains what each edition supports. The bounce stomp doesn't work when going faster than 400 mph. The fall-glide-hop doesn't work when going faster than 200 mph.

If you don't want the city, just use the visibility menu to take all buildings out.

If there was a way to dynamically change the text color of bitmap fonts, I'd do it. There isn't a way to do it, so the color remains as is. White has the highest contrast so I used that.

As for the errors, there are several around.

Edit: I could add another feature in the menus to suppress the unimportant error messages (like the jump error, stomp error, and the related - load errors will never be suppressed).
