(NB: It won't work if a Microdrive or any other additional hardware
 which effectively moves PROG is being used. So don't do that.)


easyfrog is a minimalistic Frogger clone, which is much too easy
(hence the name).

The aim of the game is simple - get your frog across the road and the
river. Making it over the road is simple enough, just avoid the cars.
But apparently you're some kind of hydrophobic frog, and you have to
ride on the logs to cross the river. Once you get past the river, you
should jump the frog into a vacant `home' (blank square). If you fill
all four homes, you get another level to try.

You get 3 lives, though these aren't indicated onscreen (sorry). If
you lose all of them it's game over, and the edge of the screen turns
red for a couple of seconds before a new game starts.

The controls are:

Q   up
A   down
O   left
P   right

These do auto-repeat if you hold them down, but I wouldn't recommend
doing that, it doesn't work very well.

Known bugs:

- if you dive the frog into the water, missing the logs, it (before
  dying) follows the log movement for one `frame' even though it's not
  actually on a log.

- the .tap file is big enough that I'm relying on `metadata' (the tape
  header) not counting towards the 1k total. I'm pretty sure that this
  is unofficially the case, but I don't think it was mentioned in the
  competition rules etc. last time I checked.

- it's much too easy. But you know that one already. :-)
