by vividhelix - 48 Hour Compo Entry

Symbiosis is a stealth game where each of the two protagonists can make a single noise in the alternate world. Also inspired by the single-player co-op idea behind Brothers - Tale of Two Sons.

Controls are WASD and Space for the left and arrow keys and right shift for the right. Think about the level name if you get stuck.

Contains only 5 levels, but they should be sneaky enough to give you a bit of a brain workout :)

My first full LD (did a mini LD before) and the first time I make my own pixel art.

dang this was really cool! Definitely the funnest entry I've come across so far. I was really frustrated at first, until I realized that the sound is created relative to the opposing person. After that, it got a lot more fun and interesting. ( got to level 3 without realizing that :/ )
Otherwise, great design and mechanics.

Took some doing, but I figured out the game eventually. If I'm not mistaken, the right side of the third level is unwinnable. Brought me back to the old game "The Classroom".

Very difficult and iffy, but I liked the mechanic. I'll try it again in "co-op" mode.

Very interesting concept. Wish you could call the guard multiple times in a level though.

Aug 25, 2014 @ 5:28am

Neat concept

Nice execution of the theme, very strong. Too bad you couldn't get more levels in!

Tried a few times as i couldnt understand the game at first. Perhaps you could write down the gameplay idea :)

This is pretty clever, well done.

I feel I should try it on oculus rift or something. Overall at first I was very confused, but then I understood the concept. Quite a sneaky game.

Quite enjoyed :)

Ah I didn't get at first that the position of the noise depended on the position of the character. Interesting concept!

I really enjoyed this one. Great mechanic!

A fun and simple (puzzle?) game. Its definatly more fun playing this on your own as I imagine its intended to be played. The only thing I didnt like was that it was over too quickly! Nice entry :D

Fun and clever mechanic

This was really fun. The theme comes through very well, and that mechanic is very well implemented. I wanted more levels! Great job.

Tough but fun! Some audio would have been nice, but it still worked well without sound. I'd to see more of this!

Nice idea for the game, very innovative.

Great game, loved the puzzle mechanic! I took some time to understand the game first, but managed to finish it :)

Cool idea.
The puzzles were great.

Very difficult remembering which control is which. I think a button to switch the controls back and forth would be better -- then highlight the side in which you are controlling. Neat puzzle game, but no audio.

Great take on the theme, I really liked how one's actions influenced other's world. Clever design, decent graphics and good progression. It would have been great to hear some music too tough. Great job!

mechabit says ...

interesting mechanics, bit of a head scratcher trying to work out where the sounds will be in each world, maybe add a marker to make easier. I only played the first 3 levels but I can imagine there being multiple switches that you can lure the AI into as part of the puzzle

Good puzzle mechanics.

Awesome! Fit to the theme.

Very fun puzzle game, the last level is a little difficult. the system is cool, but I think explanation in-game can be useful. Meanwhile, very good !

A well-crafted puzzle game with a novel mechanic (at least to me!). Good stuff.

Its difficult! But nice mapping! Nice concept!

Sep 2, 2014 @ 1:49am

Pretty cool idea. Parallel stealth. It's actually really tricky! At first, I wasn't sure where the end of the levels were, as the first level has the guards over top of them. Perhaps a tutorial level showing where to go, then introduce stealth? In any case, this was pretty fun. Nice work for your first ever LD entry! :)

adharris says ...

This is one of the most fun entries I've seen. I had some trouble with the arrow keys / rshift controls. I think it would work really well with a controller and two thumb sticks. I'd also like to see levels that involve moving the baddies more than once. Great job! Keep developing this one!

Very cool gameplay concept that took provides a nice challenge.

Sunflower says ...
Sep 2, 2014 @ 1:12pm

Interesting idea, took me a little bit to figure out, though I still found it hard to predict how the guards will move. Oh well... ^^"
(also, it could use some sounds, I think)

jomomomo says ...
Sep 2, 2014 @ 8:08pm

Not sure if i liked the randomness of how the enemies moved or not.

Took me a bit to figure out what was happening but once I did I really enjoyed myself.

Didn't get what to do in the second level.

Hey, you asked me to let you know if I wrote up a post-mortem of my game, and I just did so! So, here it is:

The little figures are really awesome, a bit hard to understand to the max.
But after a while i got it.

Cool idea, the puzzles were a bit simple but overall a very nice entry!

dhargan says ...
Sep 9, 2014 @ 1:49am

nice puzzle game! good job mate !

Sep 9, 2014 @ 6:48am

I had a hard understanding that the noise was generated were the other character was standing. Maybe you should explain it better because apart of that, it's a great idea and a nice execution!

Sneaky, sneaky! Very clever mechanics, I wish it had more levels.

5/5 for innovation, very unique game you have here. With improved graphics and controls (audio too), this could be a very cool game. Also, it took a bit to get the mechanic down but that was the point.

Snicklodocus says ...
Sep 10, 2014 @ 8:36pm

Cool idea and good level design. Could have used some audio, but I understand the time constraint. Good job!

MerlijnVH says ...
Sep 12, 2014 @ 8:54pm

Nice entry! I think the implementation doesn't work well sometimes, nothing happened when I performed certain actions, but I get what you were going for and liked the concept a lot. Good job!

SketchyGalore says ...
Sep 13, 2014 @ 11:07pm

This was a very creative idea! Excellent use of the theme, too! Gameplay-wise it had the right amount of challenge, though the "look back" mechanic was always a little easy to exploit on the second guard (typically I just made him turn to face a wall). Excellent work!

Hypnohustla says ...
Sep 14, 2014 @ 5:10pm

Took me a while to understand, after that it was nice puzzling. :)

Sep 15, 2014 @ 6:56pm

This game is a bit tricky to understand but is a lot of fun, could do with a few more instructions and a bigger gameplay area the characters can move around in.

Sep 16, 2014 @ 3:51am

Cool game! I included it in part 29 of my Ludum Dare 30 compilation video series, if you’d like to take a look :)
