Hah, I remember this one! The subs fire more often here and I think your extra time is awarded differently too, if I recall.

Yeah I didn't follow it too closely, just a bit of fun really and to learn Pico 8.

But I played this a lot as a kid :)

You captured the look quite well. Nice to do an obscure game too, plus I don't think the original had an indication as to how many shots you had remaining you could fire off, but it's a nice touch.

definitely has that atari look and feel. :D

Did 1030! That was very very slow but also very very cool. Well done!
