Hi, 

I know this post doesn't fit in this group, but since I didn't find
any alt.games.dos or *.classic or anything like that I post it here
where I hope to get help...

The game I'm searching for must have been released before 1989,
perhaps even before 1987. It already used (16 or 256? I'm not sure)
colors at ega resolution. I played it on a Kontron 286 10MHz PC with
640kb DOS MEM and 340kb extended MEM onboard. The gameplay was as
follows:

You control a little green figure (looked like a bird or sth...) just
using the arrow keys. The playing screen showed some kind of ocean
with lots of sinking little isles on it. Some went down pretty fast
and some lasted longer. The goal  was to get the coin on the isle in
the upper right corner of the screen. You always start on an isle at
the left bottom of the screen. To get the coin, you had to find a way
over the sinking isles (after a while, they popped up again). On some
of them were balls, blue balls, dark red or light red, as far as I
remember. The blue balls gave you some extra points where the light
red balls gave you lots of points or an extra life. The dark red were
dangerous. They could be a trap (isle sinks immediately and you die)
or call a monster (some big red ugly thing on two legs trying to get
you) or give you points or extra life.

Every time you collect a coin a new field of isles appeares with a new
coin in the upper right and you starting at the lower left. The farer
you got the smaller and more became the isles (start was about 4x4
isles and while you collect coins you get up to levels with 10x10
isles or so).

So please, if anybody can remember that little funny game, would you
please help me?

Thanks so far,
Ice
