I thought this game was up there in my favorites as a kid, don't think me or my younger sibling noticed personally, but the puzzles were really hard for sure. Either way we beat it between each other taking turns I remember. Oh yeah, the tank controls were a little less shit with a gamepad - back when there was a dedicated port for those no less

I also remember these games easier to beat before the internet was so pervasive and these kinds of things were the best way to pass rainy days, we'd draw out notes and maps on paper and all sorts of stuff to beat them - different times now, people's attention is way more scattered
