I tried to find Maggoo's email address but I didn't find it... so I'll report this here:
I think I found a bug... I was playing my last life and then I ate the last dot of the current stage and got caught by an enemy at the same time. It seems I cleared the stage without dying (the toothbrush came too) but at the beginning of the next stage, it showed I had no lives left... so it switched to game over.
*L* that is not an easy one to reproduce
I'll look at the code and see find what might have happened.
