I have just published my old-skooly swarm shooter game on Desura.
from the Debug Formulation web page;
http://iterationgames.com/debug-formulation/The game plays like many old-skool arcade shooter games however with some new challenging twists. When most targets are destroyed they drop a pod, these pods must be collected by the player (increasing the players pow meter), if the pods fall past the screen bottom the target will re-spawn. The player has a dual use cannon system that will fire a shell if one is loaded and will fire a rather short range shell-propulsion blast each time the cannon button is pressed. This dynamic is strategically complicated by the fact that holding the fire button will start the cannon cycling, the longer the button is held the faster the shells are loaded, however no propulsion blasts will fire in this case. When the cannon is cycling the ships engine is also accelerated (from the recycled propulsion-blasts) allowing the player to move progressively faster as well as deeper up the screen. The max firing rate is also limited by the number of pods collected. (meter top left) It is much harder to explain than play!
The free demo gives you most of the first three waves to battle. The full game is unlimited. Planed updates include; online high-score table, and achievements.
Anyway have a look here;
