Mind over Matter

by kneeko - 48 Hour Compo Entry

Can you draw an octagon while doing arithmetic? See how well your two worlds are connected.

Click and hold to draw.
Type answers with numeric keys.
Space or return to clear your input faster.
Escape to quit or restart.

Linux users will need the LOVE packages available at

I've added a patch post-compo to allow for numpad input and fixed a startup crash.

Nice job, very unique take on the theme. Though I wasn't very good at it, I guess my worlds aren't very connected.

I like your interpretation of the theme. At first it was difficult, but after a few tries I got the hang of it.

Awesome game!
The graphics is so clean and beautiful, the background music also fits the overall feel.
The game is very interesting and innovative. The combination of the left brain and right brain is mapped to the rational world and emotional world, or, the mathematics world and the art world.

Great job!

17 isn't too bad for a first go, right..?
I thought I'd have more trouble than I did.
Nice unobtrusive sound effects.
The number pad didn't work for me though, is it supposed to..?

Thanks for the nice comments everyone!

Xeke_Death: that was unintended (my keyboard doesn't have a numpad) but I don't think I'm allowed to fix it. I'll patch it if I can get confirmation that it's OK.

I get modules/SceneManager.lua:26 attempt to call setLineJoin

any idea to fix it?

Which platform? It sounds like you might have an older version of LOVE installed. If you don't mind getting messy and would like it to run, you can download the source and comment out that line (26 in modules/SceneManager.lua, comments are '--'). I will fix it tomorrow if you don't mind the wait!

Argh, multitasking. Creative take on the theme. It has a very polished feel to it. Pretty hard!

Can't play :(

Error: modules/Background.lua:32: bad argument #2 to 'draw' (number expected, got userdata)

This concept rocks.

Well that is definitely a unique idea and it messes with your head in a good way XD.

Maximum score was 18 (nothing impressive) but dear GOD some of those problems just don't work out with drawing makes it feel so hard (yet they are so simple in truth).

I liked the sounds and the music as well as the graphics, everything seemed really cool and easy to understand.

Well done! :)

pjimmy: Which version of LOVE do you have? That line uses a function new to LOVE 0.9.0.

figuratively broke my brain.

Wow, this entry is both really unique and really well polished. I am terrible at doing math under time pressure so I got the majority of my points by doing the drawing. After a while I found the tactic of trying to type in the answer during the small loading time that the drawing has when you complete one of them.

I could actually see this being used in a school to help kids get better at math, games that offer a competitive aspect offer great motivation to keep improving your score. I think that this is the highest or second score that I have given a Compo entry, Well done!

Great idea for a game, a little bit hard for me though.

For something that's kinda simple in style it works so well. I spent forever trying to figure out a calculation as I was too busy connecting the dots. Works really well! Also the art is super simplistic but works well too :)

IMPORTANT NOTE: If you want to place in the final results, you NEED votes. The easiest way to get votes is by rating other games. Judging lasts for 3 weeks following the end of Ludum Dare. For best effect, rate 20 games as soon as possible. Rating more games is encouraged.


TEAMS: Teams entering the Jam should pick a single representative to submit your game, or create a team specific account you can share. We currently do not support Team Voting, but sharing an account and together playing and rating games is acceptable.

NOT LOGGED IN?: If you get a message about not being logged in, even though you are, it’s because your web browser cached the non-logged in page. You can fix this by either refreshing your cache or clearing your cache. CTRL+F5 in many browsers. Chrome is a bit more work. Press F12 to enable Developer Mode, then you can right click on the refresh button and select “Empty Cache and Hard Reload”. This option is unavailable if you are not in Developer Mode.

PORTS: Ports to other platforms can be done after the deadline. That said, the sooner you finish your port, the sooner people can play your game, improving your chances of placing in the final results. For best results, provide a Web version of your game, or a Windows version with no dependencies. Also be sure to rate about 20 games to improve your visibility.

MY GAME DOESN’T SHOW UP: If you can’t find your game, it’s usually because the URL to your downloads are missing ‘http://‘. Fix your URLs ( and you will show up.

MY GAME CRASHES, IS UNBEATABLE, OR I MADE A TYPO: We allow you to fix crash or win condition bugs after the deadline (in a sense, like “porting” to support more players). We also allow “typo” bugs. I.e. A true that should have been a false, a word that should have been a different word, very tiny changes that you would have caught if you had more sleep. We leave this open to interpretation, but generally speaking your game should be identical to the game you submitted. No new features, just things you messed up last minute. Typos.
