You know, when you say that, it seems really obvious. I honestly didn't think it through any further than "People like free stuff! I'm gonna give away more cool free stuff!" I didn't even decide to have two demos until an hour after I uploaded the first one. Sorry for any confusion. I have re-labeled and re-uploaded the demos to make it clear which one I designed specifically for the compilation (which is basically a mini-version of the complete game, covering the first 12 stages) and which one I designed as a fun "out-take" version of the game with beta build graphics and first-draft puzzles that didn't make the cut for the final game. Thanks for checking in!
