A fun little game! I really like the momentum based gameplay, and the procedurally generated terrain makes the game really replayable. The art style looks really nice, and the music and sound effects are great!
There are some issues I had with the game though, firstly, I would appreciate if there was a quick restart button, as this game seems to be meant to be tried repeatedly, a way to quickly restart instead of waiting for the game to end when you lose momentum would be great.
The initial gameplay seemed a little confusing, as I knew you were supposed to press Space to go down, but no idea how you gain altitude when you crashed into the side of a hill. Though after I slid down a slope for the first time and got to fly pretty high, I managed to get the hang of the game and it became really fun.
The game not being able to full screen was a little sad, as I feel the art would do well on a larger screen. A larger screen would also allow the camera to show more, as when the dragon flies really high up, you’re pretty much guessing what the terrain is like below and hoping you are pressing space down toward a slope.
Sliding on the ground like a snake seems to be a better way to play the game than flying, which seems a little counterintuitive to the dragon theme.
A really well polished and really simple game! I do hope for a few bug fixes and slight changes to make the game more fun, but the general gameplay mechanic is really great already!
