Hey all. I'm gruebite and this is my 7DRL entry: GreedyRogue (loosely inspired by the BSD game "Greed"). This year I'm going for a more traditional idea: cavern, dragons, treasure, escape. I'll post the bigger progress updates here. Anyway, here is the idea:
Story
You play as a Rogue looting treasure from a Dragon's Lair under a volcano. You've picked a time when the Dragon is out terrorizing the local village. Unfortunately you didn't anticipate there being Dragonlings. But you're greedy and anxious, and continue anyway.
Mechanics
Play centers around managing the Rogue's health and anxiety in a dynamic environment. Anxiety is constantly increasing, and must be managed by collecting the limited treasure throughout the lair. Health can be lost in traditional ways, and is difficult to recover. The goal is to collect as much treasure as you can, and book it for the exit.
The lair itself is dark, and there will be some light play. Lava rivers and pools provide light, as well as dragonlings, and your candle. Objects close to light can be seen, objects farther outside the radius will be vaguely recognizable. The lair is also dynamic: Stalagmites you can push to kill dragonlings, or create bridges over lava; Boulders to push; Earthquakes creating falling hazards, closing and opening chasms.
Dragonlings will initially be asleep, but more will wake up the more treasure is collected. Dragons move randomly, breathing fire (which melts treasure), and will pursue you if they see you.
This is a very rough mock-up of the lair:
Good luck to everyone!
