@Ego: I was initially planning to put together some sort of level select, and may have done so later if I had time. By the time I realized how long it took to beat for a first-time playthrough, though, I felt uncomfortable with trying saving, which I hadn't really done before. The game was made in Game Maker! Code has been kinda' scary to me for a while, but I found some good tutorials for Game Maker's coding language, and the syntax is generally very easy to read.
@sergiocornaga: Hah! Sorryyy. I can't help but feel that at least some of the complaints I got about that level could be resolved if I'd just put in checkpoints. I only had about 24 hours left by the time I started receiving complaints, and I still had to put in a menu and credits, which proved... surprisingly challenging, so checkpoints had to fall to the wayside.
I'm glad you guys like the audio! I'm not good at making visuals beyond the very simplistic, so I felt that some good sounds would be the best way to really sell the presentation and give it some life.
