Wow, tons of content, great job on that. Very ambitious project, as an RPG needs a ton of writing and branching choices to really be compelling but there are the seeds of something really cool in here.
Although it's a pain to say, as you had such little time, but a little more variety in the music would make the whole thing a little less repetitive ;) But that's the most obvious advice ever. The boss fight seemed very arbitrary too, I had no idea what would do damage and when. It seemed that pressing Right > Left was the only reliable way to reduce the golem's health bar but that might have just been coincidence.
Once again though, good work!
RE: Slum Runner. I maaaay work more on it. I had another mechanic (access cards) already built but didn't have the time to make levels for it, especially as each level had to continue the story somewhat. Unfortunately the way I built the game (super hacky) made each level a real pain to build, and then with the story interludes I'd have to refactor to allow multi-stage levels or write content between each level for the foreseeable future :P
So we'll see, it depends on how it's received and how much work it will be to probably code the whole thing again and perhaps see if a real artist is interested ;)
