For the past year I've been working on my own spire-like game, provisionally called project dreams.
It is currently quite playable but quite bland looking and needs more content.
Nevertheless, I am trying to raise some awareness and gather people with some interests in playing and improving the game, in order to create a virtuous cycle of motivation. I've been doing my own "boosting" so to speak, with not much traction, so I'm not turning towards the FOSS game community and hoping to find other interested people there.
I have decades of experience in playing card games and even acted as lead-design in one, but making a video game solo is difficult and I work better if I have people to bounce against. So if anyone wants to help, I can use all sort of collaborators. Writers and Artists primarily, but I can totally make use of game designers and programmers, or even just people playing the game and giving me ideas for new enemies and cards.
