You've done a great job on the game's animations! However, the platform colors are too similar to the background, making it hard to distinguish between them during gameplay. Also, I would also suggest adjusting the jump height, or the platform height. In the level two, I keep bumping with another platform above, it makes me feel like I’ve lost control and causes me keep fall into the pit. Luckily, you placed enough lives for me to finish the game.
