Some details I noticed :
The position screen says "Positon"(unless my screen is buggy XD) And about that screen, the game appears misaligned on my Vectrex. However, not too much on the vertical position, but a lot on the horizontal position. I read that it's a common issue with Vectrex, so maybe the option to change the screen position in both vertical and horizontal positions would be useful or feasible?
Also, I'm not much of a hi-score guy, but maybe a time count in-game would prompt peopel to do so speed-run/scoring on your game? Just throwing that idea, I don't know if that's a possible thing? Score being counted on the time you took to beat a level and the oxygen you lost to the ennemies?
Thanks for the feedback.
I can't believe I never spotted the typo in POSITION!! Several other people never spotted it either but I pride myself on my proof reading... ah well!
Regarding calibration/positioning there's only so much I could manage and horizontal positioning broke a bunch of stuff and I was at a point where I really couldn't go back and work it all out! I learnt a lot whilst writing Big Blue which can help me with the next game... lots of things to avoid!
Good ideas regarding scoring... I was never too happy with the scoring ... many times I was going to have no score and just treasures found... as with many things they didn't make the final game as I'd been writing the game and learning at the same time and expanding and it got to the point where it wasn't too easy to add anything more.
