Let's Peek - Sulphur Nimbus: Hel's Elixir
Before I begin with any description, here are the relevant links.
Support the Kickstarter and get the demo from here: https://www.kickstarter.com/projects/1933452375/sulphur-nimbus-hels-elixir

So, here we have a request from a single-person game developer to make a video on a demo of their somewhat recently Kickstartered game. This is the same developer that created the game Patapony that I played years ago, and that video is how the dev found me.
This game feels pretty solidly put together, but the intentionally steep learning curve on the flying may be a sticking point for some people. It's a fun little game, and if the old 3D collect-a-thon style gameplay appeals to you, it's probably worth a look.
One last link: Speedup music is "Get on the Bus" from the Bound Together album, downloadable here: http://www.wushuplaya.com/boundtogether/
