Honestly just about all of these theme choices are really good. Even the ones I 0'd are good. I'll explain my -1's because I feel like it idk - My issue with on/off is that I'm struggling with coming up with a unique spin on it; I'm worried that that theme will result in games that are very similar to one another - I don't tend to like themes that seem to put restrictions on the player, because it's really hard to make losing something a fun aspect of a game, which is why Leave Something Behind is -1 - Honestly I just don't want to have to code 2 separate games for Everything Changes at Night that's just like a personal skill thing, the theme in concept isn't bad - Summoning, like on/off, leaves me with only 1 good idea (which is a card game), and I don't want this jam to become "who can make the best card game; the game jam" - It follows you is I think a little too vague; I can't get a grasp at why something following me would matter, or how to make it interesting because I have so little to go off of.

PSA: Don't be toxic, these are all decent themes and I have definitely seen worse
