TLDR; What a great experience. I really enjoyed every part of taking place in Ludum Dare 42. I would really appreciate any feedback / comments on the game.

This was so much fun! I was really excited for this weekend, and it was all worth it. Great experience, with all you could imagine, I felt pretty good overall the entire weekend, seemed to had a concept in mind all the time.
Since I am from Germany, the theme got announced at 0:00am local time on Saturday. I did a quick brainstorming session coming up with some ideas and started working on some basic art - some of it actually made it to the game. I then went for a 5 hour sleep before starting into Saturday - main development day.
Everything basically went pretty smooth. I had my concept, followed my keynotes and had a running game by the end of the day. I also managed to include some basic menus and had almost all graphics done. To reenergize I had a nice 7 hours of sleep before waking up for the final countdown.
For Sunday that left me with polishing, level design and sound as my main points of focus. I wanted to start music and sound no later than 3pm, so that I had enough time to add everything into the game and eventually build and fix some bugs. In terms of time management I think I did pretty good overall (it went better than I expected :P), but got stuck on some sound-questions in the end. I did not want to add footstep or jumping sounds, since we are in space. But it felt like the game was pretty quiet, which is why I opted for some more ambience and environment sounds. Sadly time ran out quickly and not all of my recorded stuff made it into the build. I also wish I had planned a little more time on level design, since I wanted there to be a little more content.

For the final hour it all went super crazy. I had a basic publishing chain in mind, basically I wanted to use github pages for web publishing and provide an additional windows download. However due to two gamebreaking bugs I had to rebuild twice and that took away almost all of the submission hour. At least I could work on the ldjam game page and readme file while unity was trying to build without collapsing and crashing.

Retro Perspective: Excitement all the way, hectic at the end and overall I am just very reliefed that I managed to finish something to show within the time limit.

I enjoyed taking part in such an event and will certainly participate in more game jams in the future!

I would really appreciate any reviews / comments. Feel free to give me any feedback.
