Never played it on the amiga but finished it on the megadrive.
I really enjoyed it and I'm always a bit confused by the level of dislike people have for this.
Maybe I need to play it again to see why.
What you've done looks incredible. The background and the clouds. Imagine if games that looked and moved this well had come out for the plus and gx4000.
All people could use to say their machine was better would be sales numbers

The sprite needs a bit of work and the outlines of the mountains is a bit too thick, not that I would complain if I'd bought the full game in the90's I'm just saying to offer feedback now as it still is wip.
