Been plugging away at Retromancer development and put together a handful of GIFs of both old and new content:
Since very early on, I had a test background with just a pile of pixelated bones in the middle of it for all the stages. I finally got around to adding some nicer borders and backgrounds that change for each set of stages now. These are the ants and wasps that make up the last stage of the first area: the woods.
This is the very first level, so it's relatively sedate, but the explosive shot power-up stands out nicely since the screen isn't too crowded.
The second area is the swamp, and it's full of evil trees, will-o-wisps, and other generally swamp-dwelling things. At the moment, the trees are the only enemies in the game that don't move, but that actually makes them interesting to have to deal with in a way, so I'd like to get at least one more static creature implemented.
After the swamp, the player heads to the crypt and runs into a variety of skeletons. The last batch are slightly on fire and explosive.
The caves come next, and are filled with monsters that drop blobs of poison or leave trails of webbing behind.
The last two areas, the ruins and the void, are populated by crazed cultists and eldritch horrors. Both those areas still need quite a lot of work; only one monster there (the Eldritch Cube) is anything close to fully developed so far.
