I like seeing scratch games in this jam, it makes me nostalgic for when I used to use it as a kid.
Though I have to admit there isn't much to the game. I was never big into games where its the same thing over and over like Flappy Bird or clicker games, so I wasn't a huge fan of the game play.
The lack of sound I think is also a bummer. Just a little sound when jumping or when the cube hits a spike and turns into a red cube would be neat.
Congrats on submitting though!
