This is really confusing. Often I solve a level and then press by mistake escape instead of return and my tape is lost.> But I see that the 'Replace old Tape?' message has totally disappeared

Well, no -- you just have to press the "Space" key (or "Return") to continue. I thought it would be nice to be able to watch the level continue without the player (after the player entered the exit), but I already feared that this would cause more confusion than joy.
I will change this somehow in the next version. Suggestions appreciated!
Maybe it's too difficult to code, but my suggestions would be this:
Immediately show the menu message ("Tape saved!" / "Replace old tape?") but keep the level running while this menu is shown. Is that possible?
