Tempest-inspired arcade game. Just playing around with perspective and collisions.
Avoid yellow, red, and white enemies, or shoot them if you can.
Collect 3 Level Bars to advanced to next level. (Level 3 is endless, and may have a surprise enemy.)
Collect a "Kill" Bar to destroy all enemies on screen, but receive no points.
Move: Left/right arrow or A/D or Mouse wheel (thanks rob1221!).
Fire: F or mouse click.
Jump dimensions in Levels 2 and 3: <spacebar>.
Let me know if there's anything game-breaking, and I'll try to fix it, but this is just a learning project and not for real publication.
