I like your game a lot, because It reminds me of the first phaser game we made which was really fun. I like survival games like this where you lose if you get hit. Some suggestions for your game would be too add some movement to the bombs, remove the bounciness of the character. I think adding movement to the bombs would make it more challenging, and In my opinion, I think the bounciness would make it easier for the player to jump right after jumping.
