To me, I like jams with decent duration (2 weeks to one month), have theme I could relate with and have less strict rules. Though when it comes to feedbacks, it's sad that it's hard to get them cause for some reason, my games are not picked by anyone the jam.
Yeah, totally agree — getting feedback after a jam can be tough sometimes, especially when your entry doesn’t get much visibility. That’s actually why I started using Mouse DPI Analyzers — it helps me fine-tune my mouse settings while testing my game builds, so at least I can make gameplay smoother for players who do try them out.
