I like the game. But I think I found a typo on the game over screen. It says "press mire" instead of "press fire".

Hi Nikki, thanks for playing,

I think it's a side-effect of trying to squeeze the code in below $1000 in memory. Something in the C64 system seems to over-write a byte of the text - I wasn't able to isolate what it was. In the tape release I think the code will be relocated so it doesn't happen.
