Anyone know if Crusader by J.Morrison Micros can be completed?

[ChuckieEgg]

Hi, I played Crusader (not Cosmic Crusader) on my Dragon 32 as a teenager back in the 80's and was only able to complete a few levels so with the help of Snapshot on the Xroar emulator I thought I might actually try to finish the game. It is supposed to be 7 levels but level 7 seems to be an infinite loop. I managed to do 3 screens of level 7 then gave up. Does anyone know if it's possible to actually complete level 7 or is it an infinite loop? BTW I couldn't find any walkthroughs or cheats for this game online.
