Nice platformer, although I was confused based on the screenshots since after trying the win32 and win64 versions it seemed like a one level demo. It was a pretty tough level either way, although the 32bit plays a lot different with bigger jumps. I would suggest making the first level a tad easier, since with the win32 the jumps were too tight to maneuver around spikes easily, but with win64 jumping over the eagle took really precise timing. I'd say this is a solid demo overall, and I think the art style is really cute

I really liked the art and design. I'd recomend the dash instantly recharging when the level starts or restarts after you die. That way you can immediately restart after dying instead of waiting a second or two.
