This demo is... awesome. I can't believe how good the pixel art and animations are. Hell, even the voice acting is awesome :) Plus the gameplay and controls are flawless (please just add one feature to quit the game). Just one little downside: I think that the music does not match the game. But besides that, it is one solid ingot of awesomeness, and I mean every word.
Well, I'm no musician, but the music you have sounds kind of atmospheric and new-age, while I was expecting for this game something more simple and upbeat - eventually with primitive instruments to give a "prehistoric" vibe, like percussions, or flute? Anyway, that's just my 2 euro cents of advice, because my personal knowledge of music is quite rudimentary.
No worries and thanks for sharing, just curious if it was a matter of old graphics/modern music kind of thing! You are right that primitive instruments would totally fit in. We do however have a sci-fi theme in the whole game so I believe our composer wanted to use the current instruments so that he can combine the more new-age vibe of sci fi better when it all comes together! Your two euro cents are super appreciated!
