edit: uploaded a newer version, fixing some graphical and sound glitches, as well as a bug with one of the puzzles (that would render it either trivially solvable, or unsolvable if you went to night and back).

edit: uploaded a newer version still, fixing a couple of game logic bugs.

    After “solving” the opposite of the pathed sun, I couldn’t really get anything. I absolutely love the atmosphere, especially what you did with the sound, and the sky was gorgeous. The fact that the suns were untextured added to the mystery. I just wish it was a little clearer, but I guess this game was made to be that way.

    Ok, after two days (and two nights) I give up, with only a night puzzle unsolved (damn! this last one is too hard!)

    One question : I noticed accidentally a small spot where you switch automatically from day to night (not the central spot). I first thought it was the solution for the last puzzle (maybe it is…) but it is quite weird though there seems to be nothing “accidental” in this game.

    So…maybe it’s a little bug?

I hope that your talent is recognized and supported, because you really show how much more powerful videogame art can be than many other mediums. In fact, I didn’t really think videogames could be serious art until I visited your website.

    Anyway, I’ll be donating, but I hope that you’ve been submitting proposals to art galleries to exhibit your work. It’s too good man.

    Quite an interesting game, but it could use a little more direction; there’s not even any indication that it’s a puzzle game, rather than just some kind of tech demo; some people have probably exited out without realizing it was even a game.

    Also, it could use hints, because as fun as it is to solve puzzles without help it’s just frustrating and boring to be unable to continue just because your thought processes aren’t lining up with the programmer’s. The night puzzles in particular are frustrating because unlike the day puzzles, where there’s the clear goal of getting the suns and the clear indicator of the suns dimming to indicate when you’ve failed their puzzle, there’s no direction of what to do at night, and only a nondescriptive sound cue to indicate when you’re on the right track. I’ve got 2 of the night puzzles solved and have no idea what to do for the other 2.

    How about just a readme in the game files with a hints section? They don’t have to give the whole solution away; here are some possible hints for the ones I’ve solved:
    Xrrc lbhe rlr ba lbhe cngu.
    Xrrc lbhe rlr ba lbhe zbgvba.
    Xrrc lbhe rlr ba gur cevmr.
    Xrrc lbhe rlr ba gur fxl.

    Oh yeah, and I found a path of discolored ground near the path of the sun puzzle, but less distinct and unconnected from that path. Does it have to do with one of the night puzzles, or it is some kind of red herring or oversight?

    I took screenshots from a few different angles, but it’s clearest to see it and to be sure it’s not just a trick of the light if you walk over there and look around; if you take “north” to be the direction you take from the central hub towards the sun in the middle of the swirly highlighted path, then this dim path is a bit northeast of the bright path.

    And one an unrelated note, I still stand by my point about hints :P

    Alright, seriously; if the final night puzzle had to do with sound, then it is very poorly implemented. I’ve wandered around for an hour with headphones in and volume turned to max, and I can’t find any clear directional guidance from the sound. Sure, it seems to fluctuate a bit as you turn, but it’s not clear; it just sounds like indistinguishable static in every direction. All of the other night puzzles have a very clear directional cue, and this one is near impossible to find even if you know what you’re supposed to be looking for.

    I’ve been going through some of your games that I haven’t tried yet, and finally played this. I am astounded, this is fantastic.

    Well, I almost gave up and turned it off after the first 20 minutes, I wasn’t even sure if anything was interactive in this world, and since it was so large, it took a long time to try any ideas that popped into my head.

    But, near the time I would have quit from boredom, I happened to bump into one of the puzzles. Once I noticed a way I could effect something, I found the next conclusion, and the next.

    I still got stuck a few times after that, but I never felt like quitting, because I was all wrapped up in the mystery. Reaching the end was a long series of those perfect “aha” moments. It was a beautiful process.

    I definitely wouldn’t include hints. Of course, I know YOU wouldn’t include hints. But I do think the game could use something at the very beginning to give the player an encouraging nudge. Something to hint at the nature of this world, and let the player know for sure that there is indeed something to be done here. It wouldn’t have to be unsubtle, just some part of the world that more obviously responds to the player, before she/he sets out into the landscape.

    Mr Lavelle,

    So desirous was I to be ‘in on’ this one that I went as far as to decode the hints above – and I’m still having trouble on some of them. The clue in Note 32 above – ‘(bccbfvgr gur ynfg) zbir njnl jvgubhg jnirevat’ – what do I ‘zbir njnl’ from? The central column of the previous sun?

    I also agree that the last of the night puzzles – concerning sound – is far too difficult. The sound is almost inaudible!

    On a more general note – and this is not intended as a criticism – do you think that games, as released to the public, need to be ‘connective’ in any ‘ordinary’ way to the players? For example, I was playing ‘Tape Dream’ by Gargonherd, and saw a comment someone had left about how to ‘interpret’ the game. In a certain sense, I think that game is uninterpretable. A better example might be really obscure poetry. Being dropped into a world like that in ‘Cities of Day and Night’, one has no kind of idea what kind of thinking needs to be employed. Do you think that a game made ‘for the developer’, as it were, is just as valid as a game made ‘for other people’?

    (Also, was there any logic behind your means of encoding of other people’s hints, or did you just pick letters at random?)
