Gryphon Peaks, my entry for the Ludum Dare Game Jam #46.

NOTE: I had provided a HTML5 build as a convenience.  But the game is best played on your desktop.  The game has issues with mouse capture and rendering (flickering shadows in Chrome) in the web build.  So if you have any issues with the controls or with glitchy graphics, try the download version, it will be better I promise!

Theme: Keep It Alive

Controls:  W/S = forward and back, A/D = strafe, R/F = up/down, mouse left = shoot, mouse move = steer

Objective: Save your gryphon nests from the attacking demon plane enemies!  They have opened portals and will surge out and attack both you and your vulnerable nests.  Destroy all the portals by attacking and killing enemies, which will cause planar crystals to spawn.  Collect the crystal and carry it to the portal to destroy it.  Destroying all portals and enemies and you win!
