Nice idea for the game! as stated in the comments in your game, I was easily able to jump over the border and stay there. XD
The game was a really nice concept and idea overall, but if I had a few suggestions that may improve gameplay:
- Increase the difficulty as the game goes by.
- Polish the dog mechanics a bit. I did like the approach you took towards giving the game a space-like environment, but what took away its realistic nature was how the double jump barely has any effect and my dog only makes it to the other platform by hitting into the asteroid.
- Maybe add a bit more variety in the asteroids?
Great game nonetheless!
