Hello! Thanks for your question!
Right now, we are not working on a sequel, but on a non-related game to YAG!
Nonetheless, we've discussed this possibility and got many ideas for that possible project :) Of course, this would include new mechanics.
Is the any new game to make Devs? This is the only game that I see?!
Currently, we are working in a new game, it will be announced soon :)
Was it FREE?!
Nope, it will cost money like this one :)
Can you release this game on Steam?!
We want to do it in the future, but we can't in this moment :(
TYSM <3
