Frog type game which came as the sequel to Riddler's Den.
For infinite lives, play the tape from the start using the program below.
Another error by Your Sinclair means that this hack does not work. To fix it, change line 30 so it reads: 30 LET t=t+(f-39990) * a : NEXT f. It will then work.

A version of this hack with the aforementioned fix is available for download via the link below.
