Code Towerby madmaw - 48 Hour Compo Entry
It's a tile matching game where you enter small programs (mostly mathematical formulas) using Polish notation.
Probably best you watch me play it on Youtube before you play as it's kind of hard to pick up, but feel free to read the instructions below...
If you're not familiar with Polish notation you might want to read up on it, but basically it means the operator goes first (instead of in the middle). For example
+ 1 2 = 1 + 2 = 3
+ 1 * 2 3 = 1 + (2 * 3) = 7
- - 1 2 3 = (1 - 2) - 3 = -4
The benefit is that precedence is implicit (no brackets) which is necessary for the game to work. The down side is that it's pretty hard to read. The game tries to help you enter valid expressions by colour coding your selection.
Green = section OK
Red = section missing parameters
Purple = extra parameters
Dark gray = invalid parameter
Longer chains of operations should, on average, yield rarer operators in the replacement tiles. The operators should be reasonably familiar, but just in case
+ 2 parameters, adds them together
- 2 parameters, subtracts the second one from the first
* 2 parameters, multiplies them together
++ one parameter, adds one to it
-- one parameter, subtracts one from it
acc one parameter, adds the parameter to the current score
tim one parameter, adds the parameter to the remaining time
Finally it's only really tested in Chrome (it's HTML5), but I have had some promising results in Android and iOS browsers.
Oooh comments! First of all, thanks for playing. Some people seem to be missing a couple of the nuances, which is understandable because the learning curve is vertical
1) You can build equations in any direction (not just left to right)
2) The first level (you only get One(s)) only gives you plus's and ones, variety increases on later levels (which are always unlocked). The first three levels are really just training levels.
3) It's a word play on the theme, because the only number you ever get fall from the top is 1 (you only get one - although this is technically untrue as you can also get zeros)
4) There is no ending or win condition as such, although the last 3 levels do have an end as they are timed. Would have liked to have a high-score server or something, but it didn't happen
5) I think RPN is short for Reverse Polish Notation, this only uses Polish Notation (so PN?)

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 (http://mysite.com/mygame.zip) 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.
