It probably doesn't look much but but have finally worked out how to get the character to move between two rooms. Will explain how in tutorial 4 (tutorial 3 will be a quick recap on sprites and palettes)

In the video the animation looks more jumpy than when actually playing it on my laptop - I think it is probably due to my screen capture software.
Don't know why, but had an issue with the character not interacting with the platform tiles correctly and walking either beyond where he should or stopping too early - managed to correct it by using the X offset option (more about that in tutorial 4 too).
