Awesome game! I really appreciate that the few "gentle nudge" hints I used were in the form of questions. Definitely got me on the right track while staying as vague as possible. The actual puzzles were really good as well and did a great job of leading me to discover all of the ways each element could interact without directly telling.

Great mechanic! I especially like how the puzzles combine math with geometry. You definitely had me with level 12, but the hints were pretty useful. The last couple of levels are quite tricky, but I did managed to beat the game.

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

Really good concept and fun little game!

Really cool concept ! Really well executed !
Good game.

Cool, I played back during the jam voting and for me the levels got frustrating complex quickly, the pacing was more manageable now I thought! when are you going to add derivatives? =)

Just AWESOME! Keep it up!

very clever game...super creative the last 3 lvls killed me though lol


Puzzle Sigma (Full Game)


omg this game was infuriating for me as a dyslexic XD But this video is so awesome! first one I have had edited for me which is wild, one of my favorite videos by far! 

Was fun to watch you two play to the end! Had some good chuckles. Btw, you played the harder version before the order of operations was fixed so extra props!



Fantastic game, perhaps the concept couldn't be taken too far without becoming tedious, but as a short game it's excellent. Still, I'm sure someone more mathematically inclined than me would love to solve some complex puzzles in this. Excellent and satisfying sound effects, too.

Very good game, even for me who hates maths, but "Z" doesn't do anything on AZERTY keyboards.

EDIT: Nevermind, it just doesn't do what I thought it would, but it works.

Add division

(1 edit) (+2)(-2)

Inconsistent rules for how blocks move through structures (I solved the lockless one by rotating through a wall where before and after that had not been possible) and an unintelligible method of arithmetic.

The music was repetitive. 

The art style was wonderful and funny, properly cartoonish.

I would recommend a more descriptive and clear tutorial, if not a reworking of your parenthetical use. Every time I see 1+2-3 in a simple math game, I want to say ((1+2)-3)=0, not (1+2)+(2-3)=2. 

say, further in the future, it becomes possible to have a string of numbers with random values as long as 4 signs long. 

A+B+C+D+E (4 +'s).

It is natural for the human brain to associate the methodology with left-to-right bracketing, two at a time.


Please come away with thIS knowing it comes from an amateur critic and a mathematically inclined mind. Best of luck with your future endeavors. 

Solid game. I suspect the "intended solution" wasn't always the one I found, given that I passed several levels without unlocking all the locks.

Congrats on making top 20 in the GMTK Jam! I wanted to reach out to ask if anyone on the dev team would be interested in participating in an interview about your experience during the jam? Interviews are conducted over Discord and presented live on Twitch.

Messaged on Discord.

Really clever game. Had some nice brain teasers.

Really great idea! Too bad I am stumbling just now over it.


thank you made me relize how much of a dumbass i am


This game is super fun. Cool concept, and I love math so that's a real bonus.

Wow. Really good game.

Great Concept. Loved it.

Really unique. Starts easy but slowly introduces more complex concepts. Well done.

BTW, Would love for you to try my game too.

It is an Action Platformer with unique controls.

Great game! It took me a while to figure out all the puzzles on my own, especially the last one where I took an hour of my time writing down equations, overcomplicating things. Haha!

Nice art, good music, very interesting puzzle mechanics. I enjoyed playing and recording it :)

I can see how the puzzles can get even crazier, if you decide to make more levels. Good stuff, dev!

Please check out the video and my channel: VladMan.

Thank you!


Wow a whole page of equations! Well your efforts were worth it - loved the video and glad you managed to beat all the levels.

The game is very beautiful, 

beautiful and a unique idea,

 only one thing: but if I want to quit the game which button should I press?

 because if i press x in windows it doesn't save my progress, thanks

There is no save feature at this time


Very good ideas !

I really like the use of operator's order and the level.

Thanks !


Amazing game, great concept. I have to admit i didn't get past level 12. Love the overall feel of the game.It is very neat.


What an excellent game!

the best game I played in this jam for the moment! waiting for the division, powers and roots (we'll come to complex numbers!)

Your game is fun. Just not too much difficult and not too much easy. Music is deeply fun and chill. I love it !
