There is no exception to this rule. There isn't a single game on BYOND that justifies a download size larger than 2 MB, much less the 10-50 MB travesties that litter the hub.
Apparently your pirated copies of Photoshop didn't come with the help files that explain image compression. You've spent so much time copying and pasting anime artwork into your crappy title screens... why not take a few more seconds to export them to a proper format? If your splash screens are larger than 30k, you're doing something terribly wrong.
To all of you who use BMP files for map elements or for displaying HUDs -- I'm going to go out on a limb here and assume that you A.) Can read, and B.) Know how to do a Google search. Here's a search term for you: PNG
That's cute that you want to use mp3s for music. Don't. Most of your games play worse than a generic third-party NES title; using real music samples isn't going to change that. If you use sound effects then go download one of the millions of freeware wav compression programs.
Heck, none of my games even weigh in at over 1 MB.
Proelium II: 600k
Acheron's Awakening: 700k
That's right, Acheron's Awakening, which has way more icons, maps, music files and sound effects than 99% of BYOND games out there comes in at 700k. Why? Because I compress all of my wav files, I use an efficient PNG format for my splash screens, and I even go as far as to edit the superfluous instrument tracks out of the midi files that I use.
If you "don't have time" to do all of that, you have no business making games in the first place.
