Thanks for the responses :)
TheMetalCarrotDev: Yes. I was aware that maybe I could be pushed very fast to the bottom, but did not think that was that fast xD We just wanted to take advantage of apperaring there the first time. Our promotion strategy is based on creating some community around the game in the mid term, but first we need to show the game to people that could want to join that community :)
redonihunter: Ok. I will think a bit more about the tagging of the game. Thanks for the suggestion. Today I posted a new devlog, but I did not see the game appearing anywhere, but as you said, the game appears in the tag listings, so it seems the game is currently indexed and the system is working as expected.
