Although its only my first submission... its probably the most complete of the three... (I had a lot of free time back then...).
Some good points and bad points about this game...
+: Unique style of 1 on 1 gameplay.
+: Intense 2-Player battle.
+: 5 levels of challenging enemies (1 Player).
+: 2 playable ships (Each with a different style of control and 3 unique combinations of weapons).
+: Decent graphics.
+: Decent choice of music.
-: No sfx.
-: Button mashing in 2-player mode can cause glitching.
-: Simple AI system.
-: Complex gameplay.
-: Slightly unbalanced weapons.
-: Might not run at the desired framerate (For people with old computers... like me...).
Also, here is some more info on the enemies:
Level 3: (HEAL) This ship has the ability to heal both shield AND armor. This will occur whenever GREEN rings pulse out of the ship.
(STEALTH) This ship also has the ability to double its speed. This will occur whenever WHITE rings pulse out of the ship.
Level 4: (FLASH) This ship will sometimes release a blinding light that momentarily turns the entire screen white.
(HEAL) This ship can also heal. However, it is at a much faster rate.
Level 5: (FREEZE) Whenever this ship turns the entire screen blue you will be unable to fire any projectiles. (that is the shock ray and smart bomb won't fire even though they are already charged)
Also, if you're wondering how to damage the level 5 ship... that's for you to figure out :).
