I am finally having occasional moments of relief, and yesterday I felt that I could perhaps enjoy half an hour of videogaming without having to "pay the fee" as aftermath.
I immensely enjoyed the last improved version of your Space invaders port! The intro screen is absolutely perfect now and adds greatly to the overall "classy" feeling that this port delivers. The mother ship sequence is now perfect and very enjoyable - I indeed get tempted to pursue it very frequently and miss a ship nearly every time just as in the original arcade!
I have the
feeling (but again: might be just a feeling) that there is a bit too much of lag in the shoot-hit-explode-shoot sequence. Undoubtably it is correct that also in the original arcade game firing is inhibited until the explosion sound and graph are both over, but I have the feeling that the next shot is released a liiiiiittle sooner. But again, it may be just bad recall.
A detail that I think can be easily improved is score memory: when the game is over but the player didn't beat the previous best score, the score of the last game session is immediately reset to zero as the intro screen is engaged. I think it could be easily programmed to be kept in memory, so that it is being kept displayed during the intro screen, side by side with the best score, and then reset only when a new game begins.
GOD is REAL. Unless declared DOUBLE PRECISION.
