This was a very promising demo. The art was great, the features that were in the demo all seemed well implemented. I couldn't seem to jump farm enough to get to the higher platforms though lol.
I noticed that the application had "(DEBUG)" in the title when I ran it, the game still seemed to work fine, but just in case that's important though I would let you know. I used the Windows64 download. Otherwise that was a really interesting movement mechanic (:
Nice video, only problem was the version you played was the one I made after the jam in javascript, which I might continue to update. The actual one I submitted was in pygame, and is more finished suprisingly :). I should have fixed the javascript version, so thats on me.
