Great game - really addictive. I hope it went down a storm at the OVGE? Is the PAL version complete yet, as I would love to buy a copy on a cart?
A quick coding question for you. How do you make the fish appear and disappear smoothly at the edges of the screen? It looks like you are not using PF0, so I presume you need to mask off the sprites according to how much is visible, or is there a more obvious solution that I am missing? The reason I ask is that I need to do something similar in Hunchy.
Thanks

My guess would be a black playfield and bit 2 of CTRLPF set, though there are certainly other ways.

Yeah, that's basically it: reflected playfield with PF0=%11110000 and black. Masks quite nicely. I did agonize over this quite a bit, by the way. I felt, and still feel to some extent, that just blanking one fifth of the screen is kind of cheap and is cheating the user. I couldn't come up with a better way, though - all the other methods I came up with were worse in the end, I decided.
