Really cool… just added to my collection! Would you like to join Creactivity #1?

seconded for the request for some sort of visual marker to tell me what layer / block a star is on. i'm really enjoying the game, but trying to suss out various distances without a guide distracts from the best part of the game, which is trying to think in terms of trees. besides that, i'm really enjoying the game!

Thanks for playing! See my reply to bugcat's post to see more info about my mishap with the grid... :)


Thank you for your game and visual educational tool! Next time I teach someone binary search tree, I would certainly let them play few level of this game.

I am not sure that this is a part of the challenge or not. Would you mind adding an inverted pyramid on the main screen so that players can tell which layers or even blocks the stars are in? Also, a sorting function for the given list would be very helpful.

Again, this is a very nice puzzle game. Thank you.

Thanks for playing and the feedback! Always fun to sneak in a bit of education to unsuspecting gamers ;)

I actually did have a pyramid like grid for the possible positions earlier on in the (whole 2 day) development cycle but decided to leave it out because of the mechanic introduced in the last few levels (which even didn't end up being that great). So I played the game mostly with the grid on myself and then when I disabled it, I had gotten so used to the positions that I didn't notice the necessity of it. Will definitely put it back in if I decide to do some kind of post-jam version of the game.

That was an excellent puzzle game!I loved how you implemented a well designed training curve in it by slowly increasing the difficulty of each level - a great pace, in my opinion. I wasn't a huge fan of the slider mechanic in the last two levels, but besides that, I had really much fun. :) I wonder if you have been a bit inspired by "World of Goo"? That was at least my first association with the game, which I tried to clarify in my recommendation article about your Ludum Dare 41 entry. :) Also, I uploaded a playthrough video of your game (without the spoiler how to find the 'hidden' game ;) ). Thank you very much for your work! <3

Best wishes,


Thanks a lot!

I weren't intentionally inspired by World of Goo but I do see the similarities. And I am indeed a big fan of it so of course it is inspired by it to some extent but that goes for a vast array of games.

Yeah, I kinda agree on the slider levels bit. I really should learn to allow myself to cut stuff that doesn't work that great even though I had used a bunch of time making it (even in a jam game).

Heh, maybe your subconciousness became alive while you developed the game. :) It's a wonderful thing, though. I'm a big fan of it myself, so I was super happy about that (regardless if it was intended or not). <3

And don't worry about the slider levels. It's nothing that damaged the experience itself - it's still a wonderful jam game, and one should experiment a bit in jams, so it's all fine. :)
