This will be tough I think.
When I was in kindergarden, late 80s - early 90s, I spent a lot of time at my friend's house. We used to play this Ninja sidescroller game. All I remember is that in one of the levels, you were outside and could jump on branches, etc in the trees. The graphics/colors were very bright, if I remember correctly.
Now here is the tricky part. His mom was a lot in Japan and other places in the world, and the console might have been a Japanese NES (Famicon), but I am not sure.
If anyone know this game, I would appreciate your reply.
