This was really fun! I like the steep (haha) balance between needing to land long jumps verses high jumps to retain the maximum speed and distance, but where the long jumps get you more distance, the high jumps allow for even better long jumps. But diving almost straight down is very hard to pull off successfully. It reminds me of the frustratingly hard Bear On A Scooter mixed with the terrain generation of Hill Climb Racing (although, HCR has only one generation of each map). Fun stuff!
Perhaps the hills could be a bit more smooth, but it's still manageable. I found a strat that works until about 130m where you hug the ground and jump a hill or two now and again. I also was able to smack myself out of the sky with one of my tail projectiles. I think it was because I launched one and it flew forward and missed the dragons so it landed on me latter. That was a goofy interaction.
Love the art for it too! The colors are really pretty and the background parallax is really cool.
Something that felt a bit off was that the fruit in the trees was often unattainable. Not that I never got fruit out of the trees, but that I missed so much and I couldn't really ever get them. Don't know if this is intentional and in which case there is not complaints.
I got pretty far and I plan to go farther
