Thanks!
The scoreboard on the regular A1200/A4000 version may be a little better now since it's now set to overlap the game rather than push the screen down, but it's a standard feature of the engine and you can see this happens on other games done with it. It's called a 'panel' in the engine's jargon, and as we speak, that's the only way allowed in the engine to write text or stats on the Amiga screen. But the engine is experimental and is evolving everyday, so you never know, maybe in the future it'll allow to overlay text directly on the play area without that panel or make the panel transition smoother.
The 'run out of picture on level2', now that's something more worrying that I can do something about. Can you tell if that happens before a player death or after, and at what exact point on the stage?
