I think it also bears mentioning that Itch is a developer-centric community. Yes, there are players around as well, but a lot of them probably don't even have a registered account and therefore aren't going to be able to comment on your projects. Even if they do have an account, they aren't necessarily compelled to comment. Players who do have accounts are mostly here for a specific type of game, not to play all of our "my first/second/third game" projects in genres that they don't care about. So unless you have in-game interaction between players, or some other space for players to interact such as your own website/forum, it is unlikely that you will form a big community here. Niche interests can sometimes explode, and maybe projects that have a special appeal to other developers will get more interaction, but these are rare occurrences. It's just unreasonable for this to be your expectation, or to beat yourself up over not having a big following on Itch. If you have a really good product, and you bring it to the right market, it will do well. This is a pretty small market with certain specific interests. People who come here for visual novels are not going to care about your platformer, even if it is an exceptionally good game, they just aren't here for that. That isn't to say you shouldn't make platformers and upload them here, but if you want to reach more people you'll need to bring that to a market where people are actually looking for that specific thing.
