Comparing with Alpha 14, it was 138MB and now it is 85MB which is critical low, giving wonderings to most players(Who had not bought the game yet) thinking its a small game and avoid purchasing it. A demo would fix it anyways.
Why its size has been reduced? Most deleted files are from Sounds and some from Main.dat.
What happened to the game's size?

Re: What happened to the game's size?
Potential customers who are thinking about Prison Architect will not be lost because of the file size. Mostly because they can't even see the file size on both the Steam store or the Introversion Store.
To answer your question, it's most likely because of the heavy optimizations that were done to the game.

Re: What happened to the game's size?
Keep in mind that 85 megabytes is 85 million bytes. That is a huge number just by itself. Actual code takes up a minority of that size, I would estimate the code is no more than 10MB. For (primarily) one programmer, without a lot of procedural code generation, even that much code would be hard to write. The rest would be resources, like sound and the sprite sheet.
Graphics would also take up a minority of the size. The whole of the game is pretty much contained in one image file, the sprite sheet. There would be few others, for the menus. In total, I would give graphics 20MB as well.
Sound is a huge space hog. Even compressed, sound files quickly reach megabyte sizes. I'd give the other 40MB to sound. I imagine IV removed some extra sound clips in this build, that would be the easiest way to cut the size in half.
*Note, I wrote this before I looked in the PA folder. My PA (Steam-edition) is 100MB. The executable, where all the code is, is 5MB. The main.dat, which I imagine is where the graphics are is 19 MB. The other 78MB is the sound.dat.

Re: What happened to the game's size?
To add to previous comments, the Mac non-Steam versions look like this:
Alpha 14:
Alpha 15:
If you scroll through that output, you will note that the biggest change is a 20 MB reduction in the size of sounds.dat, which makes up for most of the difference. One suspects that either unnecessary sounds were removed, or that the entire archive was compressed using a more efficient (or lossier) method.

If you scroll through that output, you will note that the biggest change is a 20 MB reduction in the size of sounds.dat, which makes up for most of the difference. One suspects that either unnecessary sounds were removed, or that the entire archive was compressed using a more efficient (or lossier) method.

actually 85MB is just over 89 million Bytes (89128960 to be exact) or 85*2^20
how data is calculated
1 bit (a 1 or a 0, thats it)
a nibble = 4 bit (yes this really exists)
1 byte = 8 bit OR 2 nibble
1 Kilobite KB = 1024 bytes
1 Megabite = 1,048,576 bytes OR 1024 Kilobytes
this is because data is stored in binary and 2^10 = 1024 so is a nice round number in binary

Lots of unused sounds were stripped out, that is all.

Pedantic post is pedantic. The orders of magnitude are correct, which was the point of yos233's post.
