Good thing you got you got your game uploaded!
The game itself is fun for a bit, though, maybe a bit repetitive. Maybe more types of hazards or maybe even power-ups or something could help add some much needed variety. Also, I managed to walk on one of those rising green poles and stayed on it as it carried me upward, making it impossible for any of the cannonballs to hit me, lol. I also feel like the game over screen should show the player the time you managed to last, since the goal seems to be to survive as long as possible.
Overall, nice job!
