I find very interesting to see your opinions on the Theme Voting, so i am sharing mine as well.

Automation (0) - I like this kind of one word theme because it is very broad. This particular one could provide an approach on automating machines in order to obtain a result. However, it seems to me that it would take too much time coding, i'll probably do something story-related to automation if this is the theme.

Break the cycle (+1) - Another simple it broad. It can be implemented on breaking mechanic cycles in-game, story-wise, conceptually-wise.

Control the environment, not the player (-1) - Too restrict in my opinion. Will probably lead to a lot of games where the "player" has to go to a place and you change pieces of the path and remove blockades. NO!

Each playthrough builds on the last (-1) - Don't get me wrong, the theme is good. Broad. Many possibilities of what you done once will affect you later and replay value. But i really don't think i can implement something nice in the Ludum Dare time frame. Probably would led to a lot of clunky games.

Everything grows (-1) - I don't like this "everything", "nothing", "everywhere" themes. The obvious answer would probably be a plataformer where the scenario is non-stop growing and would led you to be smashed on the roof or something. Or that kind of game where stuff are growing and you are running out of space (last Ludum Dare theme). Also no.

It only changes when you aren't looking (-1) - This reminds me of Slender. You are doing your stuff and you turn and BAM! jumpscare. It would be really fun to play the games of other people. But i wouldn't like to implement this.

Sacrifices must be made (+1) - OH YEAH. That's what i would like. It's broad. What kind of sacrifices? Your items? Your friends? Your limbs? How the lack of one of them would affect your gameplay? Your mobility will be reduced? Your skills will be removed? Like it.

Absorb your enemies (+1) - Yeah i know many people dont like it, it requires enemies, it requires that you absorb them, it narrows what you can do. But i would like to implement it so i am updooting it. Hate me.

Darkness is your friend (+1) - Another hate topic leading to stealth games where you hide on the shadows. But is that the only kind of darkness that can be your friend? Maybe the player is a vampire that would burn in the sun. Maybe darkness can be a concept that is your friend, like a place where you run from your problems.

Don't trust the game (-1) - No. No no no no no no. I can only imagine lots of games that have instructions on what you should do, and you do them, and you lose. Ha ha ha, not funny. I would probably think in something more like a concept in game, as the "game" is a deceiving something but, whatever. I really hope it sink into the bottom of forgetfulness.

Magic, but at what cost? (+1) - I little like Sacrifices must be made, but requiring magic in the mixture. I know it narrows a bit but it could led to questioning the player if is it really required to use magic. Would magic kills its friends? Its planet? ITSELF? I like it.

Making connections (0) - Its broad, i can think in a lot of options, connecting paths to progress, make connections to people in order to obtain data, anyway. I just think is meh.

One item, many uses (+1) - I saw this and though: McGyver! Ok, it would require some item system that you would operate in a lot of ways, like a swiss army knife, or water (water has many uses), which could be really code demanding but i think it's a fun theme.

Take one, leave one (+1) - Take WHAT? Leave WHAT? Heh, nice. Would led to questions to player, what to get and what to leave, what would be the drawbacks of the decision. It could be people that are you partners, and the one left behind DIES? It could be weapons and you have to work around the weapon weakness? I like it.

Two connected worlds (0) - It would require some good brainstorm to develop a cool way of two interconnected worlds operate in order to require the player to travel for one and another in order to progress, but, as Automation, i think it's too demanding for the Ludum Dare time frame. Lots of clunky games on the way with this theme.

Evolve (0) - Like the previous, very interesting but time demanding. Deal with evolving mechanics where you have a new set of skills, movement, anything requires time for polishing and we dont have time. Another set of clunky games on the way with this theme.

Lets hope for the best!

Also, would like to know your opinions on my opinions, even if is a "F*CK YOU, NANANA THEME IS GOOD".
