The idea of mixing platforming with breakout/pong is a novel concept and I think it's done fairly well. Perhaps better entwining the mechanics would help to take this idea even further. I'd recommend seeing this video (https://www.youtube.com/watch?v=i5C1Uj7jJCg) for a better idea on how you may be able to do that. Making the jump the means to shoot the ball was a nice start and having the ball take out the enemies added to this, though I feel in this instance it wasn't as rewarding as it should have been relative to how much luck is required.
Visually, the game is great considering the tiny resolution. The simplistic background works well and the sun's eyes following you is a really nice touch. Only minor nitpick is the small resolution. I'm not saying it shouldn't be small and pixely but if you edit your game the newgrounds allows you to display at different resolutions, I'd recommend trying to double it.
As interesting as the game is, it quickly becomes kinda boring. I think the reason for this is the lack of impact. The game feels quite slow and bland which I don't think is a core issue, it just need's a bit more game feel polish IE having the blocks flash when hit before being destroyed. This would help to add feel as well as convey info. For example, the dark purple blocks I'm still not sure if they take multiple hits or if they're just glitched or something because they don't do much besides occasionally moving when hit. Additionally, these wasn't much indication for the player being hit so it felt as though I was just being pushed along even though I knew I'd took damage. Perhaps a sound effect and flashing would help this, I noticed he becomes a slightly lighter blue but I only noticed this by going back and studying the damage effects. If you're interested, I'd recommending checking out (https://www.youtube.com/watch?v=Fy0aCDmgnxg) to get a better idea of how you could add feel/juice. I wouldn't say do everything but I'd suggested picking some of the things that you think would suit the style of your game, perhaps experiment.
Overall, I think that's everything. I hope I don't come across as too negative because it is an interesting idea, I just think it needs some more work to keep people playing. Hope this helps.
