A new version of DeViaNTe's G.D.P has been released recently, adding some new modes, more enemies and new scenarios to his excellent homebrewed aerial shooter.

Developer's note:

I'm very happy with this homebrew, currently unfinished, but having a fully original OST (by me).
Game is programmed in Lua, using my own interpreter LuaDEV. (Cool, yah?)
Full 3D, cellshading, multithreading... Lua will be becoming as useful as C!
This game, instead is a show of what could be done with it!

Improvements done so far (posted last May):

• New language: French!
• Better management of scenarios, (only 10-12 secs of loading time), cause decorations and obstacles are now randomized, so the scenario will have a little more randomness.
• Better looking scenarios: Trees, houses, and other decorations randomized added.
• Climatic lighting effects: Sunset, Daylight, Night ( going only with spotlights on the ship ).
• Multiplayer Arcade CO-OP mode: I'm working on a server, written in Perl, and I will host one server for the multiplayer arcade mode, that will be scenarios in randomness, fully of enemies, a "survive" mode alike but two players over wifi. (25% done, two players already on screen, movement a little bit rought at this point).
• Enemies, Objects, even decorations fully programmable, can now do patterns of movements, randomize them...
• Game will be fully Open Source, fully commented, even the Server code. Anyone who wants can view the source code, and learn how the things were done.

Further improvements (planned for this week and next one):

• Read the server from a file in the memory stick, so, everyone can host a server, and invite their friends. Instructions will be included.
• Yeah, more enemies, more weapons, more ships to select, more scenarios.
• Bosses! Even dogfight with some enemies...
• Upgradable levels in weapons, buying ammunition between escenarios. Points earned in every level.
• Achievements / Trophys: In-game achievements and trophys.
