The controls felt a little finicky and could use some work, and I wasn't a big fan of having to click "Start", press space bar, then use arrow key to jump. Felt like my hand was travelling all over the place, and it was annoying having to do between each run.
As well, sometimes whenever I crashed into something once, I was practically screwed right then and there simply because I got slowed down and kept getting hit by the same trap multiple times.
The theme was met pretty well, and the originality with the dogs was very nice.
The art, however, was stunning. As you're likely well aware, it was by far the strongest suit of the game.
It was also just a short, re-playable game made fun by it's simplicity. You aren't working towards something, you're just running. There's no goal that you're working towards, you just get to jump and listen to the music.
The music, was, as well, fantastic.
Overall, fun game that looks amazing. Good work, hope you do well!
