As soon as the theme came out, I started brainstorming ideas, which included running away from space police to get out of the galaxy, cleaning up an office or warehouse, and finally climb your way out of a building that is flooding with ink. While it wasn't a new or particularly innovative concept, I felt that it was simple enough for me to get done in a limited time with a limited grasp of physics programming and I could apply the graphical style well.
After throwing together some platformer physics, I rigged and animated a 2D silhouette character, decided that I didn't like the silhouette style, and trashed it. I then went through multiple placeholder graphics between flat art and pixel art and settled with pixel because it gave the game a nicer feel.
On Saturday, I started adding the ink mechanic and tried to decide what other mechanics to add. I wanted to add some sort of platform that would be destroyed when you stepped on it, but couldn't think of what it would be. Later, upon making the tileset, I added a crate and decided to make an explosive version of it that would blow up when you landed on it, pushing you slightly upward. I also made it so that jumping off the TNT crate would push you higher, allowing for more possibilities.
I eventually decided that I needed another mechanic and added barriers, which were enterable from the bottom, but could only be entered from the top by stomping with the down arrow key. The final mechanics to add were keys, doors, and a limited number of lives.
Most of the next day was dedicated to level design. I was originally planning to have 12-16 levels, but after the first few I realized that I didn't have enough time to add more mechanics and the game would lose interest.
The next day I played through the game multiple times, refining, and fixing the numerous bugs. I also through together some release material that would be ready for Submission Hour.
Over submission hour, the servers were creaking and groaning under the strain and I was unable to put anything out for the first twenty minutes or so. After putting the game out, I received a comment saying that the game was broken and discovered that I had forgotten a file that was required for the game to run. I re-added it, re-uploaded it, and everything was safe.
Looking back, I think I should have realized that you could fix bugs past submission hour :stuckouttongueclosedeyes:
