#1002 is inspired by a very simple game I never thought I'd like, but as a former Gorf Arcade owner, this game's sounds are exactly like Gorf, and I ended up playing it way too much last month (in M.A.M.E.,) strangely addicted to hearing the Gorfian sound effects.
Now this game is real simple, but I see lots of room for enhancement way beyond the original endless twitch play mechanic.
Star Fortress Orion:
<Click to Animate>
Battle across multiple star systems, fighting off wave after wave of aliens attackers, each wave different. Choose which star system to defend, each one randomized each time you play, knowing you may be over matched and have to flee to a different, hopefully easier one to gain a more powerful ship before you can beat it.
Instead of your fortress being destroyed by one hit, it now takes damage. Completing a wave will give you an opportunity to repair damaged sections. Progressing deeper into the game will allow you to gain a shield around your fortress providing an extra layer of protection. Rare Gravity Bombs will allow you to destroy all enemies at once in case of an emergency, but at a cost.
Add diagonal firing for certain levels. (Maybe, I might not get around to this...)
Finish designing new aliens
Add Challenging Stage ala Galaga
Add final Boss Battle against the Alien Mothership
Possibly add a second Constellation after Orion is complete.
Add sound, will probably not sound like the arcade because I'm not an expert enough in that yet.
